Lol. I know... Though some of my villains aren't too bad.
One of them is a person, an Ice Fairy, who wants to basically ruin a magical paradise and spark a war between Humans and Demons, because he was kidnapped as a kid by a Demon, and was horribly abused because he was different.
He gets immortality, and because of his evilness, was treated horribly when his powers were sealed, so he hires 8 powerful demons to do his dirty work. They all die, he's betrayed by Maxwell, and has his immortality taken away, then commits suicide because he sees no one is on his side. It fails, and he somehow gets immortality again.
His life takes an upturn after this, as he actually attempts to reform from what he did before.
