When I first read it, I was somewhat disappointed. He couldn't get the girl, everyone betrays him, only has an old man to trust, and he's his own executioner.
As for the girl, what of her? Kills the guy who betrayed her? Makes up? Honestly, it doesn't matter. You can have all that power, but its useless if you don't use it right.
Abrupt ending, with a 'life goes on, even when your super human'.
