for me, seeing as how i'm a Cowboy Bebop fan (as well as an AMG fan), i'd have to go with Vicious; he was a cold-blooded psychopath

From episode 5 - Ballad of Fallen Angels
Vicious: When angels are forced out of heaven, they become devils. You agree, don't you Spike?
Spike: I'm just watching a bad dream that I can't wake up from.
Vicious: I'll wake you up right now.
Spike: What's your rush, Vicious? After all, it's been a long time.
Vicious: Are you pleading for your life?
Spike: Hardly. Begging doesn't work on you, remember? Even if it's coming from the man who took you in and made you what you are.
Vicious: Yes, but he was a beast who lost his fangs. That's why he had to die, Spike. And that's why you have to die.
