Due to
Loads and Loads of Characters, it wasn't unexpected that
League of Legends would have some
horribly evil assholes.
- Dr.Mundo. Even as a child, he was a sadistic psychopath who performed horrific experiments on anything he could fetch. Hasn't changed one bit, despite his overall silliness.
- Singed, while not as bad as his teacher, is still a sociopathic asshole with no redeeming value who seems to have absolutely no limits as to what he won't do.
- While we're on the topic of Singed's teacher, we may as well mention him: Warwick was a sadistic, bloodthirsty psychopath before the transformation; if anything, the transformation made him even worse.
- Nocturne is known to kill summoners merely by giving them nightmares. He doesn't stop once people find out about him.
