A thought just struck my mind. Harry Potter’s last fight is all wrong. Now before you start cursing me or screaming at the absurdity of my thoughts, let me explain why I think so.
I guess you would all agree with me that Harry wins in the end because he comes out to be the real master of the Elder Wand. And the reason behind that, what Harry informs Voldemort, is:
a. The Elder Wand belonged to Dumbledore who won it after defeating Grindelwald.
b. Draco Malfoy won it from Dumbledore.
c. Harry overcame Draco at Malfoy Manor. And thus, Harry comes out to be the rightful owner of the wand.
But what we all are forgetting is that Harry was also overcome in a fight. Remember when Harry goes to sacrifice his life in the Forbidden Forest, Voldemort curses him with the killing curse Avada Kedavra.. It is another thing that Harry does not die. But at least, he was overcome, he was defeated by Voldemort.
So, what shall that mean? Voldemort is the true owner of the Elder Wand. That would mean the Elder Wand wouldn’t have rebounded the killing curse on Voldemort and thus, it must have hit Harry. And hence, Harry couldn’t have survived his last battle. Though all the horcruxes met their end, but the essence of the soul of Voldemort that still existed in his body still would have remained there.
What do you think of it!?
I see it this way. You may counter argue that Harry was not disarmed, the hawthorn wand stayed with him, tucked safely in his cloak. But does that hold significance compared to the fact that Harry was actually beaten by the Dark Lord?
Do share your views about my theory.
Note: I am considering the story of the book here, not the adapted one of the movie.
