I suppose you have a point 'cos that reminds me of Colby in All Stars where he couldn't see the benefit of keeping Jerri, he just hated her THAT much!

I don't think Kenny is like that, though. Yeah his stated reason for voting out Charlie was that he fucked up getting the immunity idol, but I'm sure Kenny weighed in all the options of tossing out/keeping in other players.
