Bev vs Mrs Carmody from The Mist
If you were trapped in a situation and had to be at the mercy of either one, whom would you choose?
Both were serious control freaks and while Bev was just an evil woman, Mrs Carmody was also crazy on top. I think I'd rather have Bev leading the charge so I can find a chance to off her than Mrs C, who could just randomly decide to pick me or anyone in the group to be sacrificed to appease whatever threat we were facing.
