I can offer up my slayer (journal yet to be made), but she'd definitely a bad apple. She's younger (I'm thinking 17-19) and just enjoys killing--thrill of the hunt, the blood, the fighting, etc. She's kind the worst because she picks and chooses, like, she'll decide one monster not worth her time and chase around another kill because it's more fun. Frequently bored, but surprising happy-go-lucky, she would probably be evil if she weren't fighting it.
