I'd like to see someone who's an asshole, but not necessarily bad.
Larry was close, but he did try to kill Lee. He was kinda justified in doing so, but we never saw him do something good.
Mike was kind of an asshole when we first met him, but he's not, really.
Vernon was determinately an asshole, depending on whether or not you threatened him, but he also beat the shit out of whoever you left behind, and stole your boat.
Then there's Kenny... There are people who unironically name themselves "TeamKennyAlways". I want someone a little less polarizing, and a little more of a total asshole. I know many people whose words are dickish, but whose actions are anything but. A character like that would be nice.
You...you actually want Kanye West to be in The Walking Dead, don't you?
