Moral theology

1842. Defense of Bodily Integrity Against an Unjust Aggressor.—(a) If the attack is equivalent to an attack on life (e.g., if the aggressor intends to mutilate or wound, but there is danger that he will kill), defense even with resultant killing is lawful.

(b) If the attack is not equivalent to an attack on life, but is very notable (as when a principal member will be lost or the person horribly disfigured), some authorities claim that defense which would cause the aggressor’s death is unlawful, because death is too heavy a price to pay for wounds. But against this it may be argued that the loss of limbs or organs is more serious than the loss of money, and, in some respects, is more damaging than violation. The civil law gives a person the right to protect himself in body and limbs, even by killing the assailant when absolutely necessary.

(c) If the attack menaces only a minor detriment (e.g., a black eye or bloody nose), certainly killing is unjustified. But the person attacked may hit harder and oftener than the assailant, if he is able, so that the latter may beware of him another time.

1843. Defense of Honor or Reputation.—When honor or reputation is unjustly attacked, the more perfect course is to bear the injury patiently and to pardon the offense, according to the teaching of Christ. But it is not sinful to defend honor and reputation, just as it is not sinful to defend life, limbs and property. How far may one go in defense of honor or reputation against an unjust aggressor?

(a) If the aggression is merely in words (as when the offender calls the other party a liar, or says that he is illegitimate), it is not lawful to use violence, at least such as would cause death; for there are other and less drastic means of defense that suffice (e.g., to answer the allegations, or even to retort the same epithets against the aggressor), and, unless the violence of even justifiable resentment were restrained, the world would be filled with disorder and homicidal violence. Innocent XI and Alexander VII condemned the doctrine that one may kill in order to prevent the spread of calumny.

(b) If the aggression is in deeds (as when the offender slaps the other person or throws mud or rotten eggs at him), it is not lawful to kill; for here also defense can be made in other ways (e.g., by bringing the aggressor before the court for punishment, or, if this cannot be done, by returning slap for slap, etc.). Innocent XI rejected the proposition that it is lawful to kill the aggressor who gave one a blow and then fled. It is only when the aggressor is continuing his attack, and imperilling the innocent party in life or limb, that the latter may repel the extreme force by extreme force.

1844. Killing of the Innocent.—So far we have spoken of the killing of malefactors and unjust aggressors, which under certain conditions is not sinful. The next subject is the killing of the innocent, that is, of those who are neither malefactors nor unjust aggressors worthy of death.

(a) The killing of the innocent by human authority, if it is done directly and intentionally, is always sinful, whether the cause be a private individual or society. But since God is the Master of life and death, He could command the death of an innocent person, as was done when he bade Abraham to sacrifice his son (Gen., xxii. 12).

(b) The killing of the innocent, if it is indirect and unintentional, is not sinful when there is a serious reason for performing an act from which the killing results; for it is lawful to perform an act from which two effects follow, if the good is intended but the evil only permitted, and there is a sufficient justifying reason (see 103 sqq.).

(a) It is an injury to the rights of God over human life, and is forbidden in the Fifth Commandment of the Decalogue: “Thou shalt not kill” (Exod., xx. 13). To judges the special command was given: “The innocent and just person thou shalt not put to death” (Exod., xxiii. 7). The man-slayer destroys the image of God, a crime so detestable that in Scripture God declares that He will revenge the blood of man, even though shed by a beast (Gen., ix. 5; Exod., xxi. 28).

(b) It is a most grave sin against the individual, for it deprives him of his chief natural good and the means of securing and enjoying many great spiritual goods. If the person killed desired or asked for death, no injustice is done to him, since he waived his right, but uncharitableness is committed, since the neighbor’s life should be loved, and the uncharitableness is greater according as the person is more worthy of love. Scripture numbers murder among the sins that cry to heaven for vengeance (Gen., iv. 10, ix. 5).

(a) the public good does not excuse, for example, if an enemy were to threaten destruction against a city unless it put to death an innocent person who dwelt in its borders. The criminal on account of his lawlessness is an obstacle to the common good, but the law-abiding citizen promotes the common good and it would be harmful to the public peace if he could be put to death without any fault of his own. The State is for the citizen, not the citizen for the State. But if the common safety depended on the sacrifice of one man’s life, charity and patriotism would require this man to make the sacrifice spontaneously (see 1169); that is, he should deliver himself to the enemy, and were he to refuse, it seems the community would have the right to deliver him. Similarly, it is not lawful to kill hostages, even though the enemy has broken faith, or killed one’s subjects;

(b) the private good of other individuals does not excuse; for example, it is not lawful to kill a maniac lest he do harm to those around him, at least unless the conditions of unjust aggression are fulfilled. Similarly, it is not lawful to kill a woman with child, in order to baptize the child;

(c) the private good of the individual himself does not excuse; for example, it is not lawful to shoot or poison those who are mortally wounded or suffering from an incurable disease, or who are old and helpless, in order to spare them suffering. But one may give a person at the point of death a medicine that may hasten the end, if there is good hope that it will cure him and other remedies are futile, for the purpose is not to kill but to cure (see 2485). It is lawful also for embalmers to puncture the heart or sever an artery of a person who seems to be dead, if there are certain signs of his death, for the purpose is not to kill this person, but to free his friends from fear that he is buried alive.

1847. Indirect or Unintentional Killing of the Innocent.—Indirect and unintentional killing of the innocent is lawful (1872) only when there is a reason of sufficient gravity (i.e., one of a value proportionate to the life of the innocent person).

(a) The public safety is such a sufficient reason. Thus, in time of war it is lawful to attack a city, even though the death of many non-combatants will result, or to charge the enemy, even though innocent persons have been placed by the latter as a shield to his front ranks.

(b) Private safety from death is not a sufficient reason, if it does not compensate for the loss, or if it is secured unlawfully (see 104). Thus, if Balbus cannot escape from an unjust aggressor without running down and killing an unbaptized infant or a man whose life is very necessary for the community, the temporal life of Balbus does not compensate for eternal life lost by the infant in the first instance, and the mere private good of Balbus does not compensate for the public good sacrificed in the second instance. Again, if Caius cannot escape from drowning without pushing a shipwrecked companion from the only plank which is insufficient for both, or if Sempronius who has been sentenced to death for crime cannot escape execution unless he kills his guard, the means of securing safety are unlawful.

(c) Private safety from death is a sufficient reason, if it compensates for the loss and is secured lawfully. Hence, if the life of the innocent person is only of equal importance, self-defense against an unjust aggressor by means of flight that will involve the innocent person’s death does not make one guilty of homicide (e.g., Titus is speeding in his car in order to escape a pursuer bent on murder and he cannot avoid hitting and killing a cripple who crosses the road). If self-defense is conducted by means of attack, one may use violence against the aggressor (e.g., one may shoot at him, although an innocent person whom he is using as a shield will be killed), but not against the innocent person (e.g., one may not shoot at the innocent person in order to deprive the aggressor of his shield, nor may one hold the innocent person before one in order that he receive the assailant’s bullet).

1848. Destruction of the Unborn.—(a) Direct and intentional destruction of this kind is unlawful and is known as feticide, when the fetus is killed within the womb, or abortion, when a non-viable fetus is expelled from the womb. It is not abortion to hasten the birth of a viable fetus (i.e., one which is about six or seven months old and can live outside the womb), since the child can be kept alive, but grave reasons are required to make it licit, since it presents a risk to the child’s life. But to deliver or expel a non-viable fetus is abortion. Every direct abortion is regarded by the Catholic Church as murder and is penalized with the censure of excommuuication (Canon 2550, Sec. 1). It might be argued that the direct killing of what is surely a human being is murder, but when does the fetus become a human being? The ancient theory of Aristotle, followed by St. Thomas and most medieval authors, maintains that the embryo did not become human until some time after conception, an opinion that still has great probability physically. Others maintain that animation is simultaneous with conception. Since we do not know the exact moment of animation, the moment of conception must be accepted in practice as the beginning of human life. Probabilism is ruled out in this instance, for there is no doubt about the law and its application: we must not directly kill what is probably a human being. Accordingly, abortion is considered to be murder.

(b) Indirect and unintentional killing, or rather permission of death, is not unlawful in such a case, when there is a proportionately grave reason, such as the life of the mother. Thus, it is permissible to give the mother a remedy necessary to cure a mortal disease (e.g., medicinal drugs, baths, injections, or operations on the uterus), even though this will bring on abortion or the death of the fetus; for the mother is not obliged to prefer the temporal life of the child to her own life. But the baptism of the child must be attended to, for its salvation depends on the Sacrament, and the eternal life of the child is to be preferred to the temporal life of the mother, if the conditions of 1166 are verified.

(c) Contemporary moral opinion considers that in tubal pregnancies (ectopic gestation) the tube itself is in a pathological condition long before rupture of the tube, as experts in obstetrics teach, and hence can be excised as a diseased organ of the human body. As such, the excision of such a tube would be in itself a morally indifferent act and, granting verification of the other conditions for the principle of double effect, could be licitly performed. (For a history of the moral question, medical testimony and full argumentation see Chapter X of _Medical Ethics_ by Charles J. McFadden, O.S.A.) Some theologians, however, believe that the tube cannot be removed unless it can be proved in each case that a pathological condition, placing the woman in danger of death, exists. The first view is accepted as sufficiently safe to be followed in practice. (See Francis J. Connell, C.SS.R., _Morals in Politics and Professions_, p. 118.)

1849. It is unlawful positively to kill the mother in order that the unborn child may be saved or baptized. When a caesarean section offers the sole chance of saving the mother’s life, it is permitted. It is seriously doubtful whether a mother is morally obliged to undergo the operation in situations where a threat to her life exists. In this case, if baptism in the uterus is possible without increasing the danger to the mother’s life, it should be attempted. When a caesarean section does not offer any chance of saving the mother’s life, but will directly contribute to her death, the operation should not be performed. One must await the death of the mother and then observe the norm of Canon 746; “Immediately after the death of a pregnant woman, a caesarean section should be done in order that the fetus may be baptized.” The procedure to be followed is outlined in medical-ethics books. (See McFadden op. cit., pp. 244 ff.)

1850. Direction in Cases of Doubt, Ignorance, or Error.—(a) In case of doubt, if there are positive and solid reasons for believing that an operation performed to save a woman’s life will not be destructive of the life of a fetus, the operation seems lawful; for in doubt, the woman, as the certain possessor of life, has the presumption.

(b) In case of ignorance or error (e.g., when a penitent asks whether a certain operation is permissible, or a surgeon in good faith performs an operation that is not lawful), either a truthful answer should be given to questions, or silence should be observed when an admonition would only be harmful (e.g., if to require the Caesarean operation from a dying mother would have no other result than to make her die in bad faith instead of good faith).

1851. Canonical Penalties for Homicide and Abortion.—(a) Homicide, if voluntary, produces irregularity (Canon 985, n. 4) and subjects the guilty party to exclusion from legitimate ecclesiastical acts or to degradation from the ecclesiastical state (Canon 2354). Moreover, a church is violated by the crime of homicide (Canon 1172). (b) Abortion of a human fetus, when the effect is produced, brings irregularity on those who procure it and also on the cooperators (Canon 985, n. 4). Moreover, those who procure abortion effectively, the mother not excepted, incur excommunication _latae sententiae_ reserved to the Ordinary, and, if clerics, they are to be deposed (Canon 2350).

(a) Thus, in reference to the intention, it is voluntary or involuntary, according as it proceeds from knowledge and choice, or as it is committed without realization of what is done or without the intention to produce death. Examples of involuntary suicide are a person who is temporarily insane on account of impending calamity and drowns himself, and a person who, attempting to frighten another by pretending to hang himself, actually strangles to death. It would be a mistake to say that no person who commits suicide is free, but no doubt a large percentage of those who kill themselves are not responsible for their act.

(b) In reference to the mode, suicide is direct, if that which is done tends from its nature to the death of the person who does it (e.g., firing a pistol into one’s brain); it is indirect, if that which is done tends from its nature to another end (e.g., to struggle with a criminal who is firing a revolver). Direct suicide is committed in many ways, all of which can be reduced to positive (e.g., the eating or drinking of deadly poison) and negative (e.g., the refusal to eat or drink anything).

1853. The difference between direct and indirect suicide is also explained as follows: (a) direct suicide is an act or omission that has but one effect, namely, death (e.g., taking deadly poison); (b) indirect suicide is an act or omission that has two effects, one of which is the peril of death. This peril of death is certain, if death always follows (e.g., jumping from the roof of a skyscraper); proximate, if death usually follows (e.g., jumping from a third- or fourth-story window); remote, if death now and then follows (e.g., jumping from a second-story window).

(a) It is a grave injury against the rights of God, for it usurps His authority, refuses Him the service He desires, spurns the gift He has bestowed, dishonors the image of God (Gen., ix. 6), and destroys the property of God: “Thou, O Lord, hast the power of life and death” (Wis., xvi. 13).

(b) It is an offense against society, for the community has a right to be benefited by the lives of its members, and to receive a return for the protection and assistance it affords them. Moreover, death by suicide is usually felt as a great sorrow and disgrace by the relatives of the departed, and it has a demoralizing effect on many persons of suggestible minds. The fact that the death of this or that man is not felt as a loss by a family or the State, but rather as a relief, is no argument; for if suicide were left to human decision, how many fatal mistakes would be made (see 460)! Persons valuable to society would rashly kill themselves, fearing in a mood of depression that they were worthless; others who could contribute nothing in material ways would destroy themselves and deprive their fellow-men of an example of fortitude, or at least of the opportunity of showing charity and mercy to the needy.

(c) Direct and voluntary suicide is a sin against the deepest natural inclination, for self-preservation is called the first law of nature (see 298), and also against that love of self which charity requires (see 1136 sqq.). Since charity to self is more obligatory than charity to the neighbor, suicide is a more serious sin than other forms of homicide. Nor is it excused by the desire of some good for self. The suicide does not better himself by his act, for, since he has not fulfilled his trust in this life, what can he expect in the next life? He escapes the lesser evils of physical miseries or moral temptations, but he incurs the greater evils of physical death and of moral cowardice and defeat, to say nothing of his punishment in the hereafter.

1855. Cooperation in Suicide.—Cooperation in suicide has the guilt of unlawful homicide. (a) Thus, those who incite, advise, command, or assist another to commit suicide are guilty of moral murder. (b) Those who carry out together a suicide pact are guilty both of suicide and of moral murder.

1856. Permission or Authorization to Commit Suicide.—(a) Divine authority could command or permit suicide, since God has the power over life and death. But whether God has ever done this is uncertain. Some argue for the affirmative from the death of Sampson, who pulled down the house upon himself saying: “Let me die with the Philistines” (Judges, xvi. 30), and of Razias who killed himself to escape ill-usage (II Mach., xiv. 37 sqq.), and from the acts of certain female martyrs who from love of God or from the desire to preserve chastity rushed to their deaths. But others think that invincible ignorance may explain these cases. The act of Sampson may also be understood as indirect suicide lawfully committed for the public good of his country.
