LEV724 We are forbidden to take revenge or bear a grudge. Rabbi Moshe Chayim Luzzatto writes that it is very difficult for a person not to take revenge. People are sensitive to humiliation and suffer greatly from it. To a person who was wronged, revenge is sweeter than honey. To go against one's nature and not take revenge when one is able to, but rather to forgo the entire incident takes great strength of character. This is easy only for angels who do not have human attributes and shortcomings. Nevertheless, it is the King's decree; the verse states so explicitly, and needs no interpretation [this verse]. Not only must you lend your possessions to someone who has refused to lend you his, but you must completely forget about the person's refusal. The evil inclination wants the incident to leave its mark, or at least be partially remembered. The evil inclination will tell you that even if you do bestow a favor on someone who refused you, at least do not do so cheerfully or do not assist him too much, or do not become too friendly with him. Therefore, the Torah writes, "Love your fellowman as yourself," literally as yourself, without distinction. (Mesilas Yeshorim, ch. 11). ... We are required to emulate God. Although a person sins and goes against God's will, He still bestows life upon that person. Moreover, at the very moment the person sins, God is endowing him with the ability to move his limbs and thus enables him to transgress! Therefore, if you do someone a favor and that person goes against your wishes, emulate God and continue to perform chesed.
