I think the two were good guys. I think Voldemort dying is a given.
Ugh... I really didn’t want to think of anybody else dying except Voldemort (or course) and Snape making the ultimate sacrifice to show all that he was a good guy.
For maximum impact (if thats what JKR is going for) its one of the five (Ron, Hermione, Ginny, Neville, or Draco).
I can’t see it being Hagrid, but I can see it being one of the “kids”.
