Is it possible, Snape was one of the Death Eaters with Voldemort at 
James and Lilys house the night they were killed.  It just seems a 
little unreasonable for him to loath Harry so much just because he 
didn't like James.  Or is there another reason to think Snape's 
unbalanced.  Just something that popped into my head.  Wanted a few 
other opinions.
