Whether a circumstance places a moral action in the species of good or evil?

Objections

Objection 1 : It would seem that a circumstance cannot place a moral action in the species of good or evil. For the species of an action is taken from its object. But circumstances differ from the object. Therefore circumstances do not give an action its species.
Objection 2 : Further, circumstances are as accidents in relation to the moral action, as stated above (Question [7], Article [1]). But an accident does not constitute the species. Therefore a circumstance does not constitute a species of good or evil.
Objection 3 : Further, one thing is not in several species. But one action has several circumstances. Therefore a circumstance does not place a moral action in a species of good or evil.
