Hmmmm.... Well then you've always got the question of "Is Heridon a good guy, or a tough guy who does good things to and for the people who deserve them?" If he's a tough guy who prefers to serve justice to those he sees fit by himself, then Heridon should leave Willy to die. But if Heridon is the type of guy who's willing to help anyone no matter what the cost may be, then Heridon should save Willy. People will have a problem with either choice, but screw them. It's not their book, it's yours.
-if its fits the character's personality,do it.if heridon can is the kind of person who can be kind enough to do that,then go for it.as long as its not out of character,you should be perfectly fine
