Harry could potentially be a Horcrux because a bit of Voldemort’s soul might have been transferred to Harry when the Avada Kedavra killing curse backfired. The love Harry’s mom protected him with unknowingly could have prevented a clean implantation of Voldemort’s soul, thus leaving Harry’s scar.
Voldemort only makes Horcruxes from important deaths. According to Dumbledore’s beliefs, Voldemort still needed to make one more Horcrux at the time of his first attempt to kill Harry. Seeing as Harry was believed to be the equal who could potentially defeat him, this was deemed fitting for his final Horcrux by Voldemort.
‘However, if my calculations are correct, Voldemort was still at least one Horcrux short of his goal of six when he entered your parents’ house with the intention of killing you.
‘He seems to have reserved the process of making Horcruxes for particularly significant deaths. You would certainly have been that. He believed that in killing you, he was destroying the danger the prophecy had outlined. He believed he was making himself invisible. I am sure that he was intending to make his final Horcrux with your death.’
Voldemort’s worst fear is death. His blind fear in it could lead him to believe that everyone shares the fear. Therefore, Voldemort might believe that by forcing part of his soul into the one person who could possibly kill him, Harry, it would make him invincible because it would require Harry to kill himself to destroy the last part of Voldemort. Voldemort can’t imagine someone willingly choosing death.
Harry being a Horcrux is a win-win situation for Voldemort. Should Harry die, Voldemort would dispose of part of his soul and the one person who can kill him. Should Harry kill Voldemort, Voldemort still would live on as a Horcrux in Harry.
Harry being a Horcrux would also help explain his abnormal connection with the Dark Lord.
Some connections:
- He has the rare ability to speak Parseltongue.
- He has the ability to experience Voldemort’s emotions as Voldemort experiences them.
- The Sorting Hat has trouble figuring out whether to put him in Slytherin or Gryffindor.
- Harry and Voldemort’s wands are “brothers,” using the same phoenix feather core.
And now, some input from our forums members!
Kritina does not believe that Harry is a Horcrux: “First, there’s the prophecy. If Harry were a Horcrux, Voldemort couldn’t be killed as long as Harry were alive, so it wouldn’t be a “one or the other” thing. If Voldemort knew Harry was a Horcrux, he would not want to kill him. The book also talked about how obsessive Voldemort was about doing everything himself, so he wouldn’t want his immortality to swing on a person, especially since the Horcrux could die well before he intends to.”
McGonagall counters, saying, “I’m agreeing with some that Harry could be the vessel for another Horcrux. If it happened accidentally, Voldemort may not be aware of it. Because of this, he would have no qualms about killing Harry. Voldemort may, however, start to question whether Harry is a vessel for his Horcrux because of the bond between Harry and Voldemort.
In book five, Dumbledore talks to an instrument in his office after Harry has the dream about Mr. Weasley. Dumbledore says, ‘Naturally, naturally - but in essence divided?’ Maybe Dumbledore is asking about whether Harry’s soul and Voldemort’s soul are still divided in Harry’s body.”
CutieCerutti also disagrees with the “Harry is a Horcrux” theory:
Although there are some good points as to why Harry could be a Horcrux, I just don’t see it happening either way, accidentally or purposely.
Purposely:
Dumbledore said it was very risky using a living thing as a Horcrux because it can think and move on its own. Dumbledore suspected that Voldemort’s snake, Nagini, is a Horcrux. And that was just a snake. Why on earth would Voldemort put part of his soul in someone he wanted to kill? It would be a waste of power and time to place part of your soul in something you were going to try and kill since he was one year old.
In the Ministry of Magic in Order of the Phoenix, when Voldemort possessed Harry for that brief period of time, he could not be inside of a body so full of love. It was excruciating to him. So therefore, how could part of his soul live in a body so full of love?
It just wouldn’t make sense. Voldemort repeatedly tries to kill Harry. That’s like committing 1/7th suicide.
Accidentally:
This seems pretty unlikely. This isn’t the kind of magic like when young wizards and witches accidentally break a glass or something. This is a HIGHLY advanced spell. Yes, a spell. Meaning there would probably need to either be an incantation of some sort or something physically being done to bind the spell. Therefore, this doesn’t seem likely.
