What If Harry Died in the Last Book?

For all the readers of the HP books, we know that Voldemort died in the last book. But what if it was Harry who died instead of him?

Well, if he died, it would mean that Voldemort survived, the war isn't over yet, and so it's not gonna be a good ending for the story. There are more ways how the story could have ended but i think JKR rushed wrapping it up that's why the ending turned out to be disappointing for a lot of HP fans. I myself was disappointed how it turned out but then, somehow, JKR has made other HP fans happy with it, and that's good for her... If Harry died, all of his sacrifices in the previous books will be a complete nonsense... So, it's good that JKR just decided to end Harry's miseries than prolonging the suffering of the wizarding world under Voldemort's hands.
