Lau (Black Butler)

Seriously people, am I the only one who has noticed this? (this rule excludes the PhantomHive servants and includes people with light অথবা white hair)I mean really every single person who has white hair is either completely evil অথবা evil at one time and now isn't. And I've read as far as I can read online and I mean EVERYONE, there are no exceptions (except servants)!! I started to notice this when I started thinking about Angela and Ash, both with white hair (or they're one person). Then Agni came with white hair, now he's no longer evil. After I realized that I just looked at the other villains...
