It depends. If I feel he has a good enough reason to it, and is sincere about apologizing (and he
better apologize), then I might let him live. I mean, if, say, someone was holding his family hostage for him to get the package, if he was told to do this or he'd be tortured, killed, ect, then I might forgive him.
If he turned out to be a drunk loser who, when seeing me after I survive says ''Oh, hey man, no hard feelings, right? Heh heh heh.'', then I'd most likely kill him.
