We're all from different worlds and different worlds have different traits and folklores regarding supernatural beings. For example, you being a wizard? In other worlds, you'd be straight-up evil because men who do magic are called warlocks. Would you like it if I said you have to be eliminated because in so-and-so's world a man doing magic is evil? I'm thinking no.
I think the best thing you can do right now is give them the benefit of the doubt, especially if they're not from your world. Not all werewolves lose control, not all vampires are evil, not all zombies are mindless.
