Scary stuff! Good portrayal of him, you've clearly thought about this hard. Just one little point; half-breed is the term given to people like Hagrid and Lupin because they aren't considered full humans. Tom would've been called half-blood or mudblood because his blood isn't pure. Though, now I think of it, your use does make sense ... I'm just being fussy, ignore me!
Very good work!!!
An excellent description of Tom... absolutely excellent. I loved his brief interaction with Dumbledore and the path he chose.
