"If you're very clearly good or you're very clearly bad, then there isn't that much internal dilemma going on, and that's not necessarily as interesting to play."

The problem is that you cannot prove yourself against someone who is much weaker than yourself. They are in a lose/lose situation. If you are strong and fighting the weak, then if you kill your opponent then you are a scoundrel... if you let him kill you, then you are an idiot. So here is a dilemma which others have suffered before us, and for which as far as I can see there is simply no escape.
