I've been trying to figure this out. There are some fairly obvious 'baddie' names e.g. Adolf, Herod, Cain, Jezebel, but also some less obvious ones which are quite popular e.g. David, Delilah.
When you choose a name, do famous historical figures with the same name influence you at all? If there was a notorious person with the same name you were considering, would it stop you using it? Would it make a difference if it was the first known person with that name?
Just wondering :)
