What are the best refutations of the idea that evil shouldn’t be done to stop worse evil?

I don’t disagree with @griffin1977, don’t get me wrong. There are current officeholders who are damn lucky I lack means and opportunity, because I sure as hell have motive.

It’s just that it’s a moral perspective that for the sake of real honesty requires accepting the risk of being quite wrong in one’s moral assessment, and deciding to accept that risk, and hence the risk that one is becoming an evil person in so acting. Kind of an internal trolley problem, if you will.
