(a) On the part of the subject (i.e., of the person who wills the evil), the intention must be sincerely charitable, proceeding from a desire that the neighbor be benefitted. Thus, it is lawful to wish that a gambler may meet with reverses, if what is intended is, not his loss, but his awakening to the need of a new kind of amusement. St. Paul rejoiced that he had made the Corinthians sorrowful, because their sorrow worked repentance in them (II Cor., vii. 7-11). Of course, the desire of a neighbor’s good does not confer the right to wrong him, for the end does not justify the means.
(b) On the part of the object (i.e., of the evil which is wished to another), it must be compensated for by the good which is intended. It is not lawful to desire the death of another on account of the property one expects to inherit, for the neighbor’s life is more important than private gain; but it is lawful to wish, out of interest in the common welfare, that a criminal be captured and punished, for it is only by the vindication of law that public tranquillity can be secured (Gal., v. 12).
1310. Is it lawful to wish the death of self or of a neighbor for some private good of the one whose death is wished? (a) If the good is a spiritual one and more important than the spiritual good contained in the desire to live, it is lawful to desire death. Thus, it is lawful to wish to die in order to enter into a better life, or to be freed from the temptations and sinfulness of life on earth. But it is not lawful to wish to die in order to spare a few individuals the scandal they take from one’s life, if that life is needed by others as a source of edification (Philip., i. 21 sqq.). (b) If the good is a temporal one but sufficiently important, it does not seem unlawful to desire death. Thus, we should not blame a person suffering from a painful and incurable disease, which makes him a burden to himself and to others, if, with resignation to the divine will, he prays for the release of death; for “death is better than a bitter life” (Ecclus., xxx, 17). But lack of perfect health or a feeling of weariness is not a good reason for wishing to die, especially if one has dependents, or is useful to others.
1311. Is it ever lawful to wish spiritual evil to anyone? (a) Spiritual evil of iniquity may never be desired, for the desire of sin, mortal or venial, is a sin itself (see 242), and it cannot be charitable, for charity rejoiceth not with iniquity (I Cor., xiii. 6). It is wrong, therefore, to wish that our neighbor fall into sin, offend God, diminish or forfeit his grace, or lose his soul. On the contrary, we are commanded to pray that he be delivered from such evils. (b) The good that God draws out of spiritual evil may be desired. Some are permitted to fall into sin, or be tempted, that they may become more humble, more charitable, more vigilant, more fervent. It seems that the permission of sin in the case of the elect is one of the benefits of God’s predestination, inasmuch as God intends it to be an occasion of greater virtue and stronger perseverance. It is not lawful to wish that God permit anyone to fall into sin, but it is lawful to wish that, if God has permitted sin, good will follow after it.
1312. Gravity of the Sin of Hatred of Neighbor.—(a) Hatred, whether of dislike or of enmity, is from its nature a mortal sin, since it is directly opposed to the virtue of charity, which is the life of the soul.
(b) Dislike, if enmity is not joined to it, is rarely in fact a mortal sin. Aversions and antipathies for others usually are either indeliberate, or have to do with what are real or fancied defects in others. Dislike is a mortal sin only when one despises another so much that one deliberately loathes even that which is of divine provenance in the other, or dislikes a real imperfection so immoderately as to inflict serious injury (e.g., by refusing pardon or the common signs of charity, by giving grave scandal, etc.)
(c) Enmity in fact is often only a venial sin, either because one wishes only a small harm (e.g., the loss of a small sum of money), or because one wishes harm, even a great harm (e.g., the commission of mortal sin), without full deliberation. Enmity is a mortal sin, however, when one deliberately wishes a grave evil (e.g., mortal sin or the loss of reputation) to one’s neighbor.
1313. Hatred Compared with Other Sins Against the Neighbor.—(a) Hatred is a graver sin than other internal sins against the neighbor, such as envy, anger; for, while each of these latter attacks some particular kind of good of the neighbor or only to a limited degree, hatred may be directed against any good and knows no measure. Thus, covetousness is directed against the external goods or possessions of a neighbor, while hate may extend to either internal or external goods. Envy is opposed to the neighbor’s good relatively, in so far as it is considered an obstacle to one’s own glory, but hate detests another’s good absolutely. The hater finds his satisfaction, not in any profit derived for self, but in his aversion for another’s good, and the harm that is wished his neighbor. This comparison here made should be understood, other things being equal, so that hatred of another’s life is contrasted with envy of his life, etc.; for, if the goods are not the same, hatred may be a lesser sin, as when hatred of a neighbor’s temporal good is compared with envy of his spiritual good. (b) Hatred of a neighbor is a more serious sin than external offenses done against him, for hatred sets the will wrong, and it is in the will that sin takes root: “He who hates his brother is a murderer” (I John, iii. 15). The external act, on the contrary (e.g., killing an innocent man), is not a formal sin when the will is guiltless. (c) Hatred is a less harmful sin to the neighbor than external offenses; for example, internal dislike and malevolence will not break any bones, as may happen from a severe blow.
1314. Why is hatred not numbered among the capital vices? As was said above (see 269), a capital vice is one from which naturally and usually other species of sin take their origin. Now, hatred of God or the neighbor, in the natural and usual course of sin, does not precede, but rather follows other sins. Hence, hatred is not a capital sin. This will appear more clearly if we distinguish two kinds of hatred:
(a) Hate of that which is truly evil and opposed to the true good of man (e.g., hate of vice), is naturally prior to other disinclinations, since rational nature first inclines one to love its good and hate its evil (see 1106).
