"What exactly has Cohen the Barbarian done that is heroic ?"
"Well … you know … heroic deeds …"
"And they are … ?"
"Fighting monsters, defeating tyrants, stealing rare treasures, rescuing maidens … that sort of things."
"And who, precisely, defines the monstrousness of the monsters and the tyranny of the tyrants ?"
"Well … the hero, I suppose …"
"Ah, and the theft of these rare items … I think the word that interests me here is the term 'theft', and activity frowned on by most of the world's major religions, is it not ? The feeling stealing over me is that all these terms are defined by the hero.
You could say: I am an hero, so when I kill you that makes you, de facto the kind of person suitable to be killed by a hero."
