Potioncat:
I think this is a very good question. We're told that lots of Wizarding 
families supported him until they found out how far he would go. We're 
told something made Regulus want out. Snape, a Half-blood joined the 
DE...wasn't he missing something in the details of the organization?

Just what did people think Lord Voldemort stood for? Was it his plans 
against Muggle-borns or his depth of Dark Arts involvement that either 
attracted or distanced the WW?
