If you guys would like, I can make a Gryffindor Death Eater.

I think it would be almost unfair to have no Death Eaters in the Gryffindor house. I mean there's one in every other house. I'm not sure how I would go about making this character though. He/She would probably have started out at Hogwarts as a regular wizard/witch and then turned over at some point. 

EDIT: Also, if I were to make this character, do you guys think it should be a boy or a girl? There are no girl death eaters so far.
