Voldemort: Born Evil or Made Evil?

This is the latest dorm-room-pot-smoker-koan that is being beaten to death discussed by my Harry Potter For Grown Ups list. There is large contingent supporting a Christological interpretation of the Harry Potter series. Their vote is that Voldemort was not made evil and will therefore be redeemed when Harry (presumably) triumphs at the end of Book 7.

While I'm all for allegorical Christian fantasy , and I'm all for using Harry Potter to open the door to evangelical witness is it so wrong for me to want to see the bad guy punished?

I've sat through enough "Have You Hugged Your Sith Lord Today?"
