8. Eric Cartman - South Park
Comedy CentralEven though he's funny and he's probably most fans' favourite character on the show, he's undeniably one of the biggest scumbags on TV, and frankly, he probably doesn't care what anyone thinks of that: we're talking about Cartman, of course. In the show, he's portrayed as an aggressive, prejudiced brat and his emotional instability develops into full-gear sociopathy later on in the show. He is manipulative, but intelligent as well, as he's been shown to be able to cook up some really morally dubious but brilliant plans - in short, he's also a major prick towards his friends and classmates most of the time. He has no remorse and unlike the other characters, has nothing remotely sweet to him. Yeah, Cartman is an occasionally irredeemable douche, but everyone loves him, and it's chiefly because he is irreverent, outrageous and downright nasty.
