I love doing theories here. I don't have an organization or anything working for me. I'm just a lonely guy sitting at his laptop, but I love theories, Now, not all the theories I've posted about have been approved, but this theory has been approved by J.K. Rowling herself.
So, I decided to share this theory with you guys. Spoilers ahead.
Here's The Theory
You might be thinking that the idea of Dumbledore being Death, or the sly character that meets the three brothers in the tale of the Deathly Hallows, but hear me out. Let's quickly recap that tale: Three brothers travel along a road. They meet a river and conjure a bridge to go across it. They are then met by Death.
He feels cheated and he tells the brothers that they have earned a gift in return for being clever enough to avoid him. The first brother asks for the Elder Wand.
The second asks for the Resurrection Stone.
The third, and most wise, asks for the Invisibility Cloak.
The Elder Wand and the Resurrection Stone are the objects that end up killing the brothers that had asked for them. However, the brother that had asked for the Invisibility Cloak had lived to be a great age, until he took it off and gave it to his son. He went with Death gladly, "parting this life as equals."
This theory states that the three Peverell brothers in the book are strangely similar to characters in the actual book. The first brother, who died for power because of the Elder Wand, may be Voldemort.
The second brother, who died for love, may be Snape (who loved Lily).
And the third, who cheated death at the end, is supposed to be Harry.
Remember, Death gave the brothers the Hallows. So, let's analyze this: Dumbledore is the one who gave the Invisibility Cloak to Harry.
Dumbledore also gives Harry the Resurrection Stone, concealed in the Golden Snitch that Harry caught in his first Quidditch game.
And there is the Elder Wand, which Dumbledore wields throughout the series.
He is the last person to use the wand before Voldemort uses it. So, all the items that were originally owned by Death were also owned by Dumbledore.
Let's take a look at the end of the Tale of the Three Brothers. In the end, the third brother gives the cloak to his son, greets Death as an old friend, and departs this life. At the end of Deathly Hallows, Harry has the Killing Curse shot at him, greets Dumbledore as an old friend in Limbo, but changes the story and returns to life.
