Which character do 당신 think is the nastiest?

mr garrison without a doubt

Mr. Hankey. Seriously, whenever he's onscreen it just...filths up the whole thing. How do 당신 even GET nastier than a sentient, family-rearing piece of poop?!

Kenny maybe...

LOL is that a serious question? obviously Cartman but in a funny way :]

Butters's parents and Kyle's mom.

Butters's parents: Mostly past their times for grounding Butters even FOR THE LEAST THING WHICH ISN'T EVEN GROUNDABLE.

Kyle's mom: Like Cartman say.
