The Illusive Man (Mass Effect)
The Illusive Man is one of those weird billionaires that thinks he can just throw his money to shape the world as he sees fit. While this strategy usually works in real life, it totally backfires on Sir Illusive. Dude spent unfathomable resources in order to push an agenda of human dominance in outer space, even raising Shepard from the dead in order to oppose the oncoming Reaper threat. Except, despite being thoroughly aware of the Indoctrination Reapers cause, dude figured he could somehow control them. Even when you're smart, that much money makes you stupid.
