Whether a human action is meritorious or demeritorious in so far as it is good or evil?

❌ Objection 1 : It would seem that a human action is not meritorious or demeritorious on account of its goodness or malice. For we speak of merit or demerit in relation to retribution, which has no place save in matters relating to another person. But good or evil actions are not all related to another person, for some are related to the person of the agent. Therefore not every good or evil human action is meritorious or demeritorious.

❌ Objection 2 : Further, no one deserves punishment or reward for doing as he chooses with that of which he is master: thus if a man destroys what belongs to him, he is not punished, as if he had destroyed what belongs to another. But man is master of his own actions. Therefore a man does not merit punishment or reward, through putting his action to a good or evil purpose.

❌ Objection 3 : Further, if a man acquire some good for himself, he does not on that account deserve to be benefited by another man: and the same applies to evil. Now a good action is itself a kind of good and perfection of the agent: while an inordinate action is his evil. Therefore a man does not merit or demerit, from the fact that he does a good or an evil deed.
