Objection 3: Further, there is a special vice opposed to every special virtue. But seemingly no special vice is opposed to vengeance. Therefore it is not a special virtue.
On the contrary, Tully (De Invent. Rhet. ii) reckons it a part of justice.
I answer that, As the Philosopher states (Ethic. ii, 1), aptitude to virtue is in us by nature, but the complement of virtue is in us through habituation or some other cause. Hence it is evident that virtues perfect us so that we follow in due manner our natural inclinations, which belong to the natural right. Wherefore to every definite natural inclination there corresponds a special virtue. Now there is a special inclination of nature to remove harm, for which reason animals have the irascible power distinct from the concupiscible. Man resists harm by defending himself against wrongs, lest they be inflicted on him, or he avenges those which have already been inflicted on him, with the intention, not of harming, but of removing the harm done. And this belongs to vengeance, for Tully says (De Invent. Rhet. ii) that by "vengeance we resist force, or wrong, and in general whatever is obscure" [*'Obscurum' Cicero wrote 'obfuturum' but the sense is the same as St. Thomas gives in the parenthesis] "(i.e. derogatory), either by self-defense or by avenging it." Therefore vengeance is a special virtue.
Reply to Objection 1: Just as repayment of a legal debt belongs to commutative justice, and as repayment of a moral debt, arising from the bestowal of a particular favor, belongs to the virtue of gratitude, so too the punishment of sins, so far as it is the concern of public justice, is an act of commutative justice; while so far as it is concerned in defending the rights of the individual by whom a wrong is resisted, it belongs to the virtue of revenge.
Reply to Objection 2: Fortitude disposes to vengeance by removing an obstacle thereto, namely, fear of an imminent danger. Zeal, as denoting the fervor of love, signifies the primary root of vengeance, in so far as a man avenges the wrong done to God and his neighbor, because charity makes him regard them as his own. Now every act of virtue proceeds from charity as its root, since, according to Gregory (Hom. xxvii in Ev.), "there are no green leaves on the bough of good works, unless charity be the root."
Reply to Objection 3: Two vices are opposed to vengeance: one by way of excess, namely, the sin of cruelty or brutality, which exceeds the measure in punishing: while the other is a vice by way of deficiency and consists in being remiss in punishing, wherefore it is written ( Prov. 13:24 ): "He that spareth the rod hateth his son." But the virtue of vengeance consists in observing the due measure of vengeance with regard to all the circumstances.
Whether vengeance should be wrought by means of punishments customary among men?
Objection 1: It seems that vengeance should not be wrought by means of punishments customary among men. For to put a man to death is to uproot him. But our Lord forbade ( Mat. 13:29 ) the uprooting of the cockle, whereby the children of the wicked one are signified. Therefore sinners should not be put to death.
Objection 2: Further, all who sin mortally seem to be deserving of the same punishment. Therefore if some who sin mortally are punished with death, it seems that all such persons should be punished with death: and this is evidently false.
Objection 3: Further, to punish a man publicly for his sin seems to publish his sin: and this would seem to have a harmful effect on the multitude, since the example of sin is taken by them as an occasion for sin. Therefore it seems that the punishment of death should not be inflicted for a sin.
On the contrary, These punishments are fixed by the divine law as appears from what we have said above (FS, Q[105], A[2]).
I answer that, Vengeance is lawful and virtuous so far as it tends to the prevention of evil. Now some who are not influenced by motive of virtue are prevented from committing sin, through fear of losing those things which they love more than those they obtain by sinning, else fear would be no restraint to sin. Consequently vengeance for sin should be taken by depriving a man of what he loves most. Now the things which man loves most are life, bodily safety, his own freedom, and external goods such as riches, his country and his good name. Wherefore, according to Augustine's reckoning (De Civ. Dei xxi), "Tully writes that the laws recognize eight kinds of punishment": namely, "death," whereby man is deprived of life; "stripes," "retaliation," or the loss of eye for eye, whereby man forfeits his bodily safety; "slavery," and "imprisonment," whereby he is deprived of freedom; "exile" whereby he is banished from his country; "fines," whereby he is mulcted in his riches; "ignominy," whereby he loses his good name.
Reply to Objection 1: Our Lord forbids the uprooting of the cockle, when there is fear lest the wheat be uprooted together with it. But sometimes the wicked can be uprooted by death, not only without danger, but even with great profit, to the good. Wherefore in such a case the punishment of death may be inflicted on sinners.
Reply to Objection 2: All who sin mortally are deserving of eternal death, as regards future retribution, which is in accordance with the truth of the divine judgment. But the punishments of this life are more of a medicinal character; wherefore the punishment of death is inflicted on those sins alone which conduce to the grave undoing of others.
Reply to Objection 3: The very fact that the punishment, whether of death or of any kind that is fearsome to man, is made known at the same time as the sin, makes man's will avers to sin: because the fear of punishment is greater than the enticement of the example of sin.
Whether vengeance should be taken on those who have sinned involuntarily?
Objection 1: It seems that vengeance should be taken on those who have sinned involuntarily. For the will of one man does not follow from the will of another. Yet one man is punished for another, according to Ex. 20:5, "I am . . . God . . . jealous, visiting the iniquity of the fathers upon the children, unto the third and fourth generation." Thus for the sin of Cham, his son Chanaan was curse ( Gn. 9:25 ) and for the sin of Giezi, his descendants were struck with leprosy (4 Kings 5). Again the blood of Christ lays the descendants of the Jews under the ban of punishment, for they said ( Mat. 27:25 ): "His blood be upon us and upon our children." Moreover we read (Josue 7) that the people of Israel were delivered into the hands of their enemies for the sin of Achan, and that the same people were overthrown by the Philistines on account of the sin of the sons of Heli ( 1 Kings 4 ). Therefore a person is to be punished without having deserved it voluntarily.
Objection 2: Further, nothing is voluntary except what is in a man's power. But sometimes a man is punished for what is not in his power; thus a man is removed from the administration of the Church on account of being infected with leprosy; and a Church ceases to be an episcopal see on account of the depravity or evil of the people. Therefore vengeance is taken not only for voluntary sins.
Objection 3: Further, ignorance makes an act involuntary. Now vengeance is sometimes taken on the ignorant. Thus the children of the people of Sodom, though they were in invincible ignorance, perished with their parents ( Gn. 19 ). Again, for the sin of Dathan and Abiron their children were swallowed up together with them ( Num 16 ). Moreover, dumb animals, which are devoid of reason, were commanded to be slain on account of the sin of the Amalekites ( 1 Kings 15 ). Therefore vengeance is sometimes taken on those who have deserved it involuntarily.
Objection 4: Further, compulsion is most opposed to voluntariness. But a man does not escape the debt of punishment through being compelled by fear to commit a sin. Therefore vengeance is sometimes taken on those who have deserved it involuntarily.
Objection 5: Further Ambrose says on Lk. 5 that "the ship in which Judas was, was in distress"; wherefore "Peter, who was calm in the security of his own merits, was in distress about those of others." But Peter did not will the sin of Judas. Therefore a person is sometimes punished without having voluntarily deserved it.
On the contrary, Punishment is due to sin. But every sin is voluntary according to Augustine (De Lib. Arb. iii; Retract. i). Therefore vengeance should be taken only on those who have deserved it voluntarily.
I answer that, Punishment may be considered in two ways. First, under the aspect of punishment, and in this way punishment is not due save for sin, because by means of punishment the equality of justice is restored, in so far as he who by sinning has exceeded in following his own will suffers something that is contrary to this will. Wherefore, since every sin is voluntary, not excluding original sin, as stated above (FS, Q[81], A[1]), it follows that no one is punished in this way, except for something done voluntarily. Secondly, punishment may be considered as a medicine, not only healing the past sin, but also preserving from future sin, or conducing to some good, and in this way a person is sometimes punished without any fault of his own, yet not without cause.
It must, however, be observed that a medicine never removes a greater good in order to promote a lesser; thus the medicine of the body never blinds the eye, in order to repair the heel: yet sometimes it is harmful in lesser things that it may be helpful in things of greater consequence. And since spiritual goods are of the greatest consequence, while temporal goods are least important, sometimes a person is punished in his temporal goods without any fault of his own. Such are many of the punishments inflicted by God in this present life for our humiliation or probation. But no one is punished in spiritual goods without any fault on his part, neither in this nor in the future life, because in the latter punishment is not medicinal, but a result of spiritual condemnation.
Reply to Objection 1: A man is never condemned to a spiritual punishment for another man's sin, because spiritual punishment affects the soul, in respect of which each man is master of himself. But sometimes a man is condemned to punishment in temporal matters for the sin of another, and this for three reasons. First, because one man may be the temporal goods of another, and so he may be punished in punishment of the latter: thus children, as to the body, are a belonging of their father, and slaves are a possession of their master. Secondly, when one person's sin is transmitted to another, either by "imitation," as children copy the sins of their parents, and slaves the sins of their masters, so as to sin with greater daring; or by way of "merit," as the sinful subjects merit a sinful superior, according to Job 34:30, "Who maketh a man that is a hypocrite to reign for the sins of the people?" Hence the people of Israel were punished for David's sin in numbering the people ( 2 Kings 24). This may also happen through some kind of "consent" or "connivance": thus sometimes even the good are punished in temporal matters together with the wicked, for not having condemned their sins, as Augustine says (De Civ. Dei i, 9). Thirdly, in order to mark the unity of human fellowship, whereby one man is bound to be solicitous for another, lest he sin; and in order to inculcate horror of sin, seeing that the punishment of one affects all, as though all were one body, as Augustine says in speaking of the sin of Achan (QQ. sup. Josue viii). The saying of the Lord, "Visiting the iniquity of the fathers upon the children unto the third and fourth generation," seems to belong to mercy rather than to severity, since He does not take vengeance forthwith, but waits for some future time, in order that the descendants at least may mend their ways; yet should the wickedness of the descendants increase, it becomes almost necessary to take vengeance on them.
