Speaking of sociopaths, I think Kevin Spacey got robbed losing to Jeff Daniels, drama is supposed to be dramatic, not dogmatic,

Sociopath is closer, though the term suggests a complete lack of conscience. Unlike Todd, for example - who feels nothing about his killings beyond a warped imitation of "normal" feeling ("I'm sorry for your loss," "This isn't personal"), Walt displays a conscience, shows shame, feels tormented, tries to make amends, and so on, which is crucial to making him sympathetic enough to be interesting. Nucky also seems to mean well mostly, though is a more hardened criminal type. Hannibal is operating on a different level. He might as well be a sociopath, but has a code of his own different from society's, and ends up being a weapon of justice, punishing the sinners and sparing the good like Clarice.

A misuse of clinical terminology IMO, though I did acknowledge that his incomprehension of the moral-psychological, or society, operates as a kind of madness. It's a TV show, not the observation of an actually existing person. It precisely does not - and for a number of reasons including the totally fantastical central plot concept (i.e., of the Blue Meth whose purity drives everyone to extremes) - neither WW nor any of these characters can really be submitted for diagnosis. He is an exhibit or an idea, in a morality play. The Graymatterists played their role in creating the monster, too.
