Was Quirrell a victim?

After reading the first book...again...I started to think about if 
Quirrell was a victim or a knowledgable co-conspiritor?  Did LV take 
him over because he was going to be the DADA the first year that HP 
was going to be at Hogwarts and knew that HP could easily be killed 
or was Quirrell a DE and let his master take over him so he could do 
the same?  It all depends if Quirrell was a DE or some poor guy in 
the wrong place at the wrong time.  

Personally I think Quirrell was a death eater and just doing his duty.  Quirrell put on the facade of a studdering, bumbling fool for a whole year for the rest of the school to make him the least possible suspect.  

But who did suspect him?  Snape, a past death eater.  Snape could have known about Quirrell and his history as a DE, that is why he kept his watch and knew to check the Stone while everyone was after the troll.  

Was Quirrell ever in Azkaban?  I wonder.  If Quirrell was  a DE, wouldn't have DD known or Snape told him?  That is my only monkey wrench... Does anyone have 
any other theories???
