Fist of all, I would like to apologize if this has been posted 
before.  I couldn't find it anywhere in the archives.  Okay, when 
Voldemort was "killed" the first time, (incident that resulted in 
Harry's scar) he was able to come back.  He was able to become a 
parasite off of Quirrell.  Then, finally, in book four, he got his 
body back.  So what I'm asking is, if Voldemort can keep on coming 
back like that, how can they ever really kill him?
