Ultron. He's a robot who wants to destroy humanity because he sees their sins on this planet. He thinks machines are the superior beings and wishes to make them the only beings. It's scary because he's got a point. Humans are just the worst and machines outwit us in every way, like who cares if you're the world's smartest man since Einstein when google exists?
Then again there's Thanos who in the comics pursues genocide because he's got a hard on for a skull girl. Damn man he's just like me...
