Whether an individual action can be indifferent?

Objections

Objection 1 : It would seem that an individual action can be indifferent. For there is no species that does not, cannot, contain an individual. But an action can be indifferent in its species, as stated above (Article [8]). Therefore an individual action can be indifferent.
Objection 2 : Further, individual actions cause like habits, as stated in Ethic. ii, 1. But a habit can be indifferent: for the Philosopher says (Ethic. iv, 1) that those who are of an even temper and prodigal disposition are not evil; and yet it is evident that they are not good, since they depart from virtue; and thus they are indifferent in respect of a habit. Therefore some individual actions are indifferent.
Objection 3 : Further, moral good belongs to virtue, while moral evil belongs to vice. But it happens sometimes that a man fails to ordain a specifically indifferent action to a vicious or virtuous end. Therefore an individual action may happen to be indifferent.
