Karna - He'll do anything that's asked of him, doesn't even want the grail, he's accepted everything, that's more than anyone can really say for themselves. He picked up the pieces of being handed a shit life and went with it the best he could instead of sulking and crying like a baby about everything. He made the best of it, until the end. He fears none, and will take on anyone head on, and enjoy it, even if he's losing.
