The Red Skull is hardly a super villian too, but hey he is consider one any way. Yes he did try to take over the world under Hitler (in the old 1940's comics anyway) I tought Red Skull was pretty cool as a villian even if he was working for Hiter. It was the 40's and I can understand why they had the Red Skull in that time. To help the soldiers morals and suff with Cap.
But Bats is not super, yet we aruge his place along side the greatness super heros ever, the same applies with Joker, He ant super but he is aruge with the greatness villians ever.
