There were alot of people got severely injured at the end of the the book...so do they die in the next one?...I will not answer. When the battle starts at Hogwarts, there are a few people injured right off the bat. Then some more in the beginning of the Deathly Hallows. Someone even gets bit by a werewolf in 1/2 blooded prince. I won't tell you if they live or die...but you'll never guess who. Otherwards than Dumbledore, Aragog dies.
