LAST EDITED ON 12-03-10 AT 11:15 AM (EST)That's a good question, kiki.
I think it has mainly to do with Russhole clearly outlining his strategy from the get-go and justifying what he was doing as part of the game. By contrast, NaBonkers isn't trying to do anything strategic whatsoever and is in it completely for herself. Russhole knows the importance of having an alliance partner and he wouldn't have been openly talking about sabotaging others in front of tribemates while NaBonkers doesn't give a shiv and thinks nothing of openly sabotaging Kelly B's leg.
Yes, both are clueless when it comes to thinking they're unbeatable to everyone else in the game, but Russhole is sneakily despicable in the context of gameplay while NaBonkers is openly despicable without caring about the game's outcome. I think that's the main difference between these two as it's easier to respect that Russhole was trying to play the game a certain way even if we didn't like some of what he did.
