also, since we are trimming anti-heroes Donald Duck can go.. I defended it before but he doesn't qualify as an actual sociopath (like Patrick) and although he does have Villainous Jerk moments I think he has too much remorse to be a truly heinous anti-hero.

same with Mr. Bean (despite me, again, defending it in the past).

Patrick differs from both of those two in the fact he's never shown any lasting remorse, especially in modern times.. heck, even Daffy Duck shows more remorse than Patrick these days (and Daffy is a classic example of a true Villainous Jerk (far moreso than Donald or Bean).
