Everyone is the hero in their own story. I think this holds true for most people, but some people certainly know they're evil and what they're doing is evil. Putin knows he's an horsefeathers, the "bad guy" and he simply doesn't care. Same thing with Trump. Nah, these dudes are narcissists. They know that they’re doing wrong, but in their mind, it’s for the greater good and one day they’ll get the praise they deserve. Bauer’s just a creep, along the lines of Armie Hammer, who thinks that since there’s no law against sexual deviance, so long as it’s consensual-ish, he must be in the right.
