After finishing Harry Potter and the Deathly Hallows I, at first, felt satisfied with the ending. However, after letting all the information settle I came up with a very important question.

As you all know by now, Voldemort unintentionally made Harry a Horcrux the night he tried to kill him (something I had suspected). Also, Voldemort was made into a Horcrux for Harry when he used Harry's blood to achieve his rebirth in the Goblet of Fire.

In order to make a Horcrux one must split their soul by committing an act of pure evil. Obviously Voldemort had done this the night he tried to kill Harry, so that unintentional Horcrux makes perfect sense to me. However, what about Harry's Horcrux? Harry committed no act of evil that night in the graveyard, so then how was his soul split?

My theory on this is that Voldemort created the Horcrux for Harry, since killing Cedric and then using Harry's blood for his rebirth were both acts of pure evil. Then by using Harry's blood in his own body he had placed a piece of Harry's soul inside himself.

What are your thought? Did you all find this hard to follow/figure out?
