Most people seem to go for the charismatic figure. It's interesting how much of a backlash there is when it turns out that they were just human after all, people feel betrayed and manipulated for having placed that figure on a pedestal.

The stories about Steve jobs were always there (the most telling of which I thought was when he ripped off Wozniak with the Atari situation, but Lisa said a lot too), and gates was a dick in his time too.

Interesting people tend to have a few sides, and some of those sides can be pretty ugly.
