At the risk of being way too late for the party (I just finished BCS), I'm confused by people's attitudes on Kim. I don't really think she's the best or the worst person. She seems simultaneously sympathetic (towards Jimmy) and self-absorbed (enough) that she gets driven to do most of the horrible things she did without regard for final consequences. Sure, she becomes more of the instigator later on, but I think it's the result of her hitting a sort of critical mass of how Jimmy has rubbed off on her. The whole Howard plotline just felt like a fixation that she couldn't let go of and couldn't see where it would lead, but not one motivated by malice. Does that make her evil?
