The villain I love to hate!
Here's the thing about Kilgrave: He's the worst. There's no master plan, no sob story that makes everything he's done understandable. He's selfish and sadistic, which is what makes him a perfect villain. Given his character, he would have been a terrible person without his power. But once he has the ability to make the people around him do anything he says he becomes this incredible and dangerous force.
He's my favorite villain because he's so well-written.
He's not evil for the sake of being evil. He's not misguided. The things that make him cruel are incredibly mundane. He sees people as objects. He feels entitled to anything and everything. He doesn't care about the feelings of others. There are so many people in the world who are that kind of selfish. And seeing that on screen clearly cast as bad is so rare.
