Fan Casting Shoot the Dog in Sort by Tropes

When a character does an ambiguously (a)moral act because current circumstances make it the most pragmatic and logical thing to do. If The Hero performs the job himself, he may even go so far as to hide it from the rest of the cast (possibly with serious repercussions later) due to the risk of compromising his moral standards, or they might say What the Hell, Hero? to which he might reply I Did What I Had to Do.
