Reminds me of that recent article that the best way to identify a narcissist is to just ask them (true narcissists will readily admit it). That line in Patton (probably my favorite movie) where he says "Hell, I know I'm a prima donna. I admit it."
Still does not pay to be an asshole though. If you want to call them assholes - I believe Jobs and Patton would have been just as successful if they had not been. But their legacies are (maybe forever) tarnished because of it.
Patton could have just as easily not gotten the chance to stage his magnificent campaign across Europe - just because of an "asshole" move. It wasn't worth it. Proves that people do still care about how others are treated.
