He's a vunerable and tormented person in there, but that doesn't stop him from being fucking AWESOME. Despite any regrets or angst he doesn't flinch, doesn't bow to anybody, and doesn't put up with anyone else's shit. Even if you somehow hurt him he'll still fucking destroy you and do it in STYLE.
WHY CAN'T MORE VILLIANS BE THIS COOL. He needs his own series. A series where he's just fucking badass, 24/7.
