Read the book and you'd know that Harry was not raised for slaughter, but that he had to die temporarily to kill the horcrux! Dumbledore did what he had to - because it was the right thing to do.
Dumbledore reveals how thoroughly he loves Harry. Harry is brave, and Dumbledore is proud as any father would be. More than that, Dumbledore succumbs to a parent's weakness; he cares more about Harry's happiness and wellbeing than the wizarding world he is trying to protect.
He wasn't in a position he could quietly withdraw from public life. So, the only place he could have raised Harry would have been Hogwarts… but in a school with children of Death Eaters (either “reformed” or in prison - Harry would have been an easy target and would likely meet with a 'tragic accident'.
Introduction. One of the most intriguing ideas in Harry Potter and the Philosopher's Stone is that Professor Dumbledore set up events so that Harry would try and stop the theft of the Philosopher's Stone by Voldemort.
Originally Answered: Why did Dumbledore sacrifice himself? He was in pain, from the curse he had due to breaking Marvolo Gaunt's ring. He probably wanted to die on his own terms. He wanted to make it appear such that Snape was playing for Voldemort's team, so that Voldemort would trust him with absolutely anything.
Draco Malfoy's mother Narcissa was cold, cunning and devoted to the Dark Lord. But she was also a mother, which meant she was willing to risk everything to make sure her son was safe. When Harry survived Voldemort's Killing Curse for the second time, Narcissa pretended he was dead so she could get to Draco.
Harry begins to show depression in the later books after the loss of Sirius and Dumbledore. After Dumbledore dies (Half-Blood Prince, Rowling, 2005), Harry seems to close in on himself and pull away from his loved ones.
Dumbledore knew that destroying Voldemort's horcruxes was the only way to truly defeat him. He believed that Harry was the one person who was smart, courageous, and perhaps lucky enough to find and eliminate all the horcruxes.
He finds out for sure immediately after Nagini's attack on Arthur Weasley. This night is significant in many ways. While Harry sleeps, he enters Nagini's mind.

Dear Petunia, It is with great sadness that I must inform you of the death of your sister and her husband. They were murdered by a Dark wizard known as Lord Voldemort, whose cruelty and violence they had been fighting for years. I tried my best to protect them, but, alas, I regret to say that I failed.
She made a promise to Dumbledore
As Lily's last remaining blood relative, if Petunia were to take Harry in it would seal the enchantment and provide him with protection from Voldemort. This would last as long as he could call the place where his mother's blood existed his home.
'Remember my last'
Petunia's disdain for Harry was most likely born from a long-standing jealousy of her magical sister, Lily. A Howler from Dumbledore, addressed to Petunia, said 'Remember my last' – no doubt referring to the letter which he left with baby Harry, on the doorstep of Privet Drive.
I trust Severus Snape completely. '”
That was why, when professor McGonagall was in doubt, Dumbledore had told her quite firmly that he would trust Hagrid with his life.
Who better to send Harry on his way from King's Cross station, with one last piece of wisdom: 'Do not pity the dead, Harry. Pity the living, and, above all, those who live without love. ' Pottermore looks back at the moments that made our favourite characters so memorable.
One is that Severus Snape is a master of Occlumency and therefore a difficult target for Voldemort to see through. The second is that Harry himself was not able to block Voldemort, and therefore the overall plan between Snape and Dumbledore was too critical to risk its discovery.
Voldemort intentionally made six Horcruxes, but when he used Avada Kedavra on Harry, he unintentionally created a seventh Horcrux. Instead of dying, Lily's love for Harry created a counter 'curse' known as Sacrificial Protection and saved Harry.
Dumbledore had to keep certain things hidden from Harry just in case Voldemort read his mind. He did not want Harry knowing that Snape brought the sword of Gryffindor for that reason, it is very likely that he did not want Harry knowing that he planed to have Snape kill him for the very same reason. Save this answer.
“Dumbledore didn't want to lose his wand at that point and Draco disarmed him. So that meant that the wand gave Draco its allegiance, even though Draco never knew it, even though Draco never touched it. “From that moment on, that wand gave its allegiance to Draco, and it wouldn't work as well for anyone but Draco.”
Dumbledore knew it meant Harry would need to die in order for Voldemort to truly die, so he was pleased to know that Voldemort's mistake in taking Harry's blood might just save Harry's life.
Dumbledore knew Snape could be extremely valuable in the war against Voldemort, so he capitalized on Severus' desire to protect the Potters by using it as an opportunity to get him on side. The end result being a deal where Dumbledore would offer them protection in return for Snape's service as a spy.
In the novels and per the plan, Dumbledore is killed by Snape during the Battle of the Astronomy Tower. In the following days, a funeral is held for the Hogwarts headteacher down by the lake, attended by all students and teachers (excluding Snape).
