Well, this is somewhat unrelated, but still related to Snape's 
deatheater past, and the Life Debts theories circling around.  I've 
always wondered something.  Why didn't Snape kill James Potter?  We 
know he was a death eater at one point-I would imagine a through and 
through death eater as well, no matter what his redemption was later 
on.  We know that he hated James Potter.  Arthur Weasley said that 
the DE's killed for fun, and what would be more fun for Snape then to 
out his old enemy?  This is early on, before any secret keeper, or 
even any Harry.  The only reason I can come up with is this:James 
Potter once saved Snape's life....
