But since it is possible for a man to do an act of injustice without yet being unjust, what acts of injustice are there, such that the doing of them stamps a man at once as unjust in this or that particular way, e.g. as a thief, or an adulterer, or a robber?

Perhaps we ought to reply that there is no such difference in the acts. 119 A man might commit adultery, knowing what he was about, and yet be acting not from a deliberate purpose at all, but from a momentary passion. In such a case, then, a man acts unjustly, but is not unjust; e.g. is not a thief though he commits a theft, and is not an adulterer though he commits adultery, and so on. 120
