That's the problem I usually see with most of the written moral rules, that through universals they are unable to recognize the particularity and uniqueness of each situation in itself. And since good is a very circumstantial thing, many times people who follow such rules do what is supposedly right, but is actually wrong, and don't do what is supposedly wrong, but may sometimes be right. It takes skill and insight to have that discernment and to know when exceptions are, in fact, right.

Good to know that she helped him.
