Severus Snape's decision to kill Albus Dumbledore in the Harry Potter franchise is one of the most debated moment among fans. When the Harry Potter franchise first released, it took the world by storm. Children suddenly didn't want to go to school because their Hogwarts letter hadn't arrived yet.
Severus Snape killed Hogwarts Headmaster Albus Dumbledore because he had been asked to do so by Dumbledore himself.
For all intents and purposes, this act only solidified Harry's suspicions that Snape was working against Dumbledore the entire time. But there were parts of the story Harry didn't know, including that Dumbledore was already dying and had asked Snape to kill him when the time was right.
These attempts on Albus Dumbledore's life were the events that led up to the Battle of the Astronomy Tower on 30 June, 1997. In the action, Dumbledore was killed by Severus Snape and not the primary perpetrator of the plot, Draco Malfoy.
We saw above that his confrontation with Dumbledore must indeed have been traumatic, as Dumbledore offered to protect both him and his mother from Voldemort's wrath and Draco was unable to kill an already dying and wandless wizard. Dumbledore's offer of refuge is exceedingly important to the Draco redemption theory.
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.
Lucius Malfoy had a strong dislike of Albus Dumbledore. This is due to two reasons – Dumbledore believed in Muggle rights which contradicted Malfoy's pure blood beliefs. In addition, Lucius was a Death Eater, so he believed that Lord Voldemort was a much more powerful wizard than Dumbledore.
Three reasons, really: firstly, as part of Harry's transition from boyhood to full blown adult wizardry, the death of Dumbledore represents the point at which Harry is fully exposed to the fight against Voldemort - his insistence on not briefing Prof McGonagall (as the new head of Hogwarts) on Dumbledore's final ...
He was more jealous of Harry than he let on
It was easy to miss because Draco didn't often show his emotions, modelling himself on his cold, confident, calculating father, but J.K. Rowling has confirmed that a lot of his enmity towards Harry stemmed from envy.
“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.”
Despite his attraction to the Dark Arts and Voldemort's ideology of wizard supremacy, Snape's love for Muggle-born Lily Evans, Harry's mother, eventually compelled him to defect from the Death Eaters. He then became a double agent for Albus Dumbledore and the Order of the Phoenix.
Later in the year, McGonagall duelled with Death Eater Alecto Carrow during the Battle in the Astronomy Tower and later learned of Snape's murder of Dumbledore. McGonagall was initially appointed as Headmistress, but was demoted after Voldemort took control of the school and placed Snape as Headmaster.
In her estimation, in an attempt to protect the true Harry's identity, Snape sacrifices Hedwig, thus keeping the other Death Eaters off his scent albeit for only a short time.
In order to conjure the avada kedavra curse, you have to want to kill your victim. We all know that Voldemort could easily kill a child without an ounce of remorse... but not Snape. Snape didn't want to kill Dumbledore, and this was why the spell was blue instead of the usual green.
In order to preserve his position as a trusted Death Eater, Severus Snape was forced to tell Voldemort the true date at which the Order planned to move Harry.
Having gone through the horrors of the second wizarding war as a Death Eater, Draco abandoned the pure-blood beliefs he was originally devoted to, and grew to become a better person than he was in his youth, growing more tolerant and accepting of the non-pure-bloods of the wizarding world.
He comes from a historically long line of Slytherins. The Malfoy family consists of an ancient line of pure-blood wizards, most of whom attended Hogwarts School of Witchcraft and Wizardry and were traditionally sorted into Slytherin House.
Draco had several reasons for lying to Bellatrix, including the fact that he was never a bad person. Moreover, he no longer found working for the Dark Lord appealing and hated how Voldemort treated his family. He did not intend to harm anyone and believed Harry was the only person capable of defeating Voldemort.
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.
Dumbledore's death was still necessary because he was going to die anyway, and he wanted Snape to remain an effective spy. If Snape hadn't killed him than Malfoy would have, ripping his own soul, or one of the death eaters would have, and Snape would have been found out.
Answer and Explanation: No, Hagrid does not die in Harry Potter and the Deathly Hallows. He survives the battle at Hogwarts, and he is later mentioned in Harry Potter and the Cursed Child, which takes place over 18 years after the battle.
Despite being a valued Death Eater in the days before Voldemort fell following his attack on baby Harry, Lucius stumbled out of favor with the Dark Lord when he squandered Riddle's diary (secretly a horcrux) in Chamber of Secrets and failed to obtain the prophecy in Order of the Phoenix.
Not knowing whether Draco was alive or dead, Narcissa chose to lie to the Dark Lord rather than risk losing her son. When Voldemort asked her to check if Harry was dead and she realised he was, in fact, still breathing, Narcissa seized her opportunity.
It is also probable that, since Narcissa's lie to Voldemort saved Harry's life, the family is pardoned for their crimes. They keep a relatively low profile after that, while continuing to live a leisurely life in the Malfoy Manor.
