I'm a huge harry potter fan. I'd love nothing more than to get to rowling's level of intellect and writing skills, but that's besides the point.
This is more of a hypothesis or question than a theory, but I still find it to be interesting. If any of you have a twitter accounts, please tweet this back to j. k., because I am truly intrigued to hear what she has to say on the matter.
anyways, so I was just recently talking to my friend about what happens when a dementor sucks out your soul, when i realized that horecruxes do essentially the same, taking your soul out of your body. According to MatPat's video on the matter, by the time that harry was 14 voldemort had less than a percentage of his soul in his body left. He still had complete control of his bodily actions, despite the fact when someone has less than a percentage more of their soul being taken out of them they are not in control of anything, which has been made very clear. Seems a bit off right? But okay, let's give rowling this one, because this isn't even the start. Here comes the meat of it.
J.K. also makes it clear that people who have been given a little smooch from a dementor are still alive, they're just useless body lumps, therefore their soul does not contribute to one's survival. yet when horecruxes are described in the movies and books, they were said to preserve one's life, and the only thing to it is the soul. But that makes no sense. But that also brings up my philosophy. lets put you in the shoes of voldemort. you make 8 horecruxes, but this time, dumbledore decides to kill you, no horecruxe destruction necessary. so what happens now? your body is now useless and failing, so would your conscious transfer to you're largest horecruxe, or would a part of your soul be transfered to your body? It couldn't be either, because, like i said, the soul isnt needed to live. J.K. Rowling, if you're reading this, please know you're my hero and I love all your work. though the world could have moved on without cursed child *cough cough*, and that I hope you enjoyed my proposition. And Riordan, if you're reading this, don't feel to smug, I have one up one you for the next post. Regardless, thanks for reading.
