Why does killing split the soul?

In fact, Voldemort’s soul was so unstable that by the time he created five Horcruxes, it split on its own when his Killing Curse rebounded the first time, which caused the fragment to be removed from him and attached to Harry.

Who is the lost soul in Harry Potter and the Sorcerer’s Stone?

In the film adaptation of Harry Potter and the Philosopher’s Stone, after Harry killed Quirinus Quirrell, Voldemort’s mangled soul left the dying body and pierced through Harry. (In the book, it is said that Voldemort “left” Quirrell, but whether he took on a smokelike physical form as in the movie goes unmentioned).

Why didn’t Voldemort know that Harry was a pseudo-Horcrux?

Voldemort wasn’t aware of Harry being a pseudo-horcrux because he didn’t plan it, and Harry didn’t know either until Voldemort “killed” him, but he actually killed the piece of soul kept in him.

Could Voldemort have seen Harry Potter if someone else killed him?

And at the very least, Voldemort could have seen if someone else were actually able to kill Harry at all. Albus Dumbledore is undoubtedly a genius and one of the greatest wizards who has ever lived. And although it’s hard to admit, the same could be said about Lord Voldemort.

Did Voldemort actually have a secret child?

Granted, it isn’t a very magical or dramatic way to round out a story, but it does make a lot of sense. So for those who aren’t in the know about this, Voldemort actually has a secret child, a girl named Delphini who was born to Bellatrix Lestrange.

What was Voldemort’s ultimate downfall?

Again, it’s no surprise that Voldemort’s ultimate downfall was his own arrogance, but you’d think after a couple of failed attempts on Harry’s life that Voldemort might hold off on the big speeches and just try to kill Harry. Had he done that, he probably would have actually succeeded.
