Evil Dumbledore, with a twist....

No Dumbledore bashing.

The twist is - Harry is evil too, and in league with Dumbledore. I have a feeling that this two can be a beautiful dynamic... The heads of houses, can be evil too...

But Weasleys and Hermione are firmly against. But make Dumbledore and Harry the protagonist. They takes care of Voldemort and Death Eaters very quickly, and then becomes the Dark Lords themselves. Bonus points if Grindelwald is either recruited by them, or against them, fighting for the 'light' side.
