I think Snape too, like Harry and Longbottom was born in the last week of July.Just imagine Dumbledore being killed as part of his own plan and every piece of jigsaw seems to fall in place.Snape is going to kill Voldemort in the end and shall be killed in order to save Harry
Voldemort will certainly die. We have to find out whom Rowling didnot want to die. It would be Malfoy as he was a changed person in last book. Rowling may not have intended to kill Snape considering the troubles he has faced in life.
i think voldy and harry because without each other the story does not goes. entire series revolves around the two of them. so its got to be both harry and voldermont are going to kill eachother.
I think Harry and Voldermort die together in the seventh book. The killing Curse is supposed to kill. Love is the counter curse but... Voldermort lost his powers. Part of Voldermort is in Harry. Harry... like Voldermort can speak Parsltounge. Harry's scar... could be a horcrux. in order to destroy Voldermort. Harry must die. Hagrid might die too. Turning coal into gold is three steps; Black White And Rubey. Sirius Black dies (Black) the Dumbbldore (White) and then Ruebeous Hagrid (Rubey) Just a thought though :)
With regards to JK Rowlings book I think harry will die as Voldermot has kept his life in 9 places. Rowling aslo was very specific that one has to kill oneself to do that. Therfore Voldermots major place where he lost his life was when he came to kill harry & that would be why that scar appeared on harrys head. so if he has to kill Voldermot, he would have to kill himself too.
