It also struck me as interesting that Mad Eye, Lupin, and Snape all die-- that curse that Snape put on the post of Defense Against the Dark Arts teacher seems to be a pretty potent one! Even Moody, who never actually filled the post, gets it.

That is what surprised me when JKR didn't kill off that ugly toad Umbridge.

I don’t think the curse was that they would die. I think it was just that no one would stay in that post for more than a year.
