Villains are villains. They aren't supposed to save the world, they are supposed to end the world. Although, there's one villain in particular who has fallen for a girl. He's never felt this way for someone, which is why he's so unsure of his feelings about this girl. He doesn't know what to feel anymore after Chrollo finds out that Feitan's been out with this girl. He doesn't know what to do when he isn't allowed to see her ever again.
