Thomas Aquinas

“ 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. ”

“ 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?" ”

“ As Augustine states (QQ. sup. Josue viii) , human judgment should conform to the divine judgment, when this is manifest, and God condemns men spiritually for their own sins. But human judgment cannot be conformed to God's hidden judgments, whereby He punishes certain persons in temporal matters without any fault of theirs, since man is unable to grasp the reasons of these judgments so as to know what is expedient for each individual. Wherefore according to human judgment a man should never be condemned without fault of his own to an inflictive punishment, such as death, mutilation or flogging. ”

“ 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. ”

“ 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. ”

“ 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. ”

“ Now the rewarding of the good does not belong to a special virtue, but is an act of commutative justice. Therefore in the same way vengeance should not be accounted a special virtue.
Objection 2: Further, there is no need to appoint a special virtue for an act to which a man is sufficiently disposed by the other virtues. Now man is sufficiently disposed by the virtues of fortitude or zeal to avenge evil. Therefore vengeance should not be reckoned a special virtue. ”

“ Nor is it an excuse that he intends the evil of one who has unjustly inflicted evil on him, as neither is a man excused for hating one that hates him: for a man may not sin against another just because the latter has already sinned against him, since this is to be overcome by evil, which was forbidden by the Apostle, who says (Rom. 12:21) : "Be not overcome by evil, but overcome evil by good." ”

“ 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. ”

“ 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 ”

“ 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. ”

“ 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. ”

“ For it is written (Rom. 13:4) of the earthly prince that "he is God's minister, an avenger to execute wrath upon him that doeth evil." If, however, a man takes vengeance outside the order of divine appointment, he usurps what is God's and therefore sins.
Reply to Objection 2: The good bear with the wicked by enduring patiently, and in due manner, the wrongs they themselves receive from them: but they do not bear with them as to endure the wrongs they inflict on God and their neighbor. ”

“ Sometimes a wrong done to a person reflects on God and the Church: and then it is the duty of that person to avenge the wrong. For example, Elias made fire descend on those who were come to seize him (4 Kings 1) ”
