I think a comparison between Troyzan and Estee's character from her Survivor fanfic, Gardner, might explain the problem with Troyzan's attitude.

Gardner was pretty sure he'd win if Alex (who had won the final Immunity Challenge when it was just a Final 2) took him to the jury instead of Connie, Alex's mortal enemy (and a total witch, to boot). But Alex figured that she'd have a better chance of winning if she took Connie than if she took Gardner (as it turned out, she still might have won if she took Gardner, but that's another story). Gardner was mad as heck when Alex voted him out -- but he voted for her at the final Tribal Council, because he was able to put his anger aside and realize that Alex had played a better strategic game than Connie.

Troyzan could not do so. It's not the anger at being duped by Kim that was his problem, it was allowing his anger to control his vote -- and being enough of a fan of Survivor to realize that it wasn't Survivor unless you were lying! If Troyzan had been clueless about the game, then I could just shrug off his inability to control his anger. But he wasn't.
