Considering the way some of the female concentration camp guards ran things, that was rather my point. They have already proven themselves to be capable of cold, calculated sadism; such as for instance, casually shooting small children for amusement.
And as already stated, in the past we had some real villainesses, such as Bathory etc. (the vampire countess, who bathed in, and drank the blood of servant girls believing it would keep her looking youthful)
Just being female doesn't automatically equate to loving and motherly. Look at the case of that recent-ish nursery paedo ring, some ugly, bloated whore bitch by the name of vanessa george got busted for being a nonce, and hitting it off with some male nonce in a paedo relationship. One of her fantasies IIRC was to kidnap, fuck and murder some small kid.
Fucking dirty bitch. Hopefully she gets raped repeatedly while inside.
