Whether passion increases or decreases the goodness or malice of an act?

Objections

Objection 1 : It would seem that every passion decreases the goodness of a moral action. For anything that hinders the judgment of reason, on which depends the goodness of a moral act, consequently decreases the goodness of the moral act. But every passion hinders the judgment of reason: for Sallust says (Catilin.): "All those that take counsel about matters of doubt, should be free from hatred, anger, friendship and pity." Therefore passion decreases the goodness of a moral act.
Objection 2 : Further, the more a man's action is like to God, the better it is: hence the Apostle says (Eph. 5:1): "Be ye followers of God, as most dear children." But "God and the holy angels feel no anger when they punish . . . no fellow-feeling with misery when they relieve the unhappy," as Augustine says (De Civ. Dei ix, 5). Therefore it is better to do such like deeds without than with a passion of the soul.
Objection 3 : Further, just as moral evil depends on its relation to reason, so also does moral good. But moral evil is lessened by passion: for he sins less, who sins from passion, than he who sins deliberately. Therefore he does a better deed, who does well without passion, than he who does with passion.
