The headmaster had never anticipated being so weak when Draco Malfoy confronted him, and the boy was, therefore, able to disarm him easily. Dumbledore must have been terrified when his wand was flung from his hand since he would have recognized that this meant its power wouldn't die with him after all.
The plot also had another unintended but fortuitous side-effect: when he came to confront Dumbledore on top of the Astronomy Tower, Draco used the Disarming Charm upon him and in so doing, inadvertently won the allegiance of the Elder Wand for himself. At the time, no one realised this, not even Draco or Snape.
But as we saw in Order of the Phoenix, Dumbledore was far too powerful for him to take on in a straight fight. Also, Dumbledore had the advantage of having the Elder Wand during their duel as well. He couldn't beat Dumbledore in a one on one duel, so he had to try to have him killed by other means.
This would have meant that Harry could not have become the possessor of The Deathly Hallows. And if Harry had not have been the possessor of The Deathly Hallows (because Draco was at that point the true master of The Elder Wand, having disarmed Dumbledore just before Snape killed him.
Why did Dumbledore let Draco disarm him on Reddit?
it occurs to me that Dumbledore may have intentionally allowed Malfoy to disarm him so Snape wouldn't become wand owner. This hints at Dumbledore having forethought (think of the Observers from Fringe mythos) as acting knowing future events need to happen.
The Elder Wand Did Belong To Whom ? (Draco? Snape? Voldemort? Or Harry Potter)
Could Dumbledore have defeated Draco?
Could Dumbledore have beat Draco and the Death Eaters if he tried to? Yes, though overall it would be pointless, and Dumbledore knew that. Dumbledore knew his days were numbered, even if he beat Draco and the intruders, he wouldn't be long for the world.
Did Harry get in trouble for using Sectumsempra on Draco?
For using Dark Magic, albeit unknowingly, to cause serious harm, Snape sentences Harry to detention every Saturday until school ends. Snape dismisses Harry's protests, as does Professor McGonagall, who later informs Harry that he was lucky not to be expelled.
Bellatrix pressured Draco to decide if the captured boy is Harry. His eyes show he recognizes Harry, but he decides not to confirm that they have indeed captured Potter. Instead, he chooses to save the hero. It could be a sign that Draco never wished Harry actual harm.
Malfoy attempted to bully Ron on his own in Philosopher's Stone but stopped when Ron hit him back. Following this, Malfoy became known as the bully who used Crabbe and Goyle as his muscle and it was obvious he wouldn't dare to speak up otherwise.
Firstly, Malfoy almost killed Katie Bell, a seventh year Gryffindor student and Quiddtich player who had been part of the DA. Katie Bell by DoraTheBrit Whilst on a trip to Hogsmeade, Madam Rosmerta (who had been herself under the Imperius Curse by Draco) put Katie under the Imperius Curse to make her…
While conferring with Snape about the inevitable outcome of this curse, Dumbledore also asks that Snape kill him when the time is right. Not only would this protect Draco from irreparable harm, but it would ultimately prove Snape's loyalty to the Dark Lord during a critical time.
Family. Snape's family background is mostly shown in flashbacks during the course of the last three novels. Snape was born to Eileen Prince, a witch, and Tobias Snape, a Muggle, making him a half-blood (hence the name, "Half-Blood Prince").
Voldemort intended Draco to die in the attempt to kill Dumbledore so that Lucius would be punished for his failure to retrieve the prophecy from the Ministry of Magic.
Harry was the true master of the Elder Wand at this point. Voldemort began to realize that the Elder Wand wasn't obeying him as it should. He believed that Snape was the true owner since he killed Dumbledore and had Nagini kill him.
In his memoir, Felton said that Fiennes improvised Voldemort awkwardly hugging Draco Malfoy. "It gave me goosebumps then, and the memory gives me goosebumps now," Felton wrote.
J.K. Rowling says Draco doesn't have a patronus because he never learned the spell but I think it's because he doesn't have any powerful happy memories to use.
The Elder Wand, however, refused to harm its true master and flipped over, flying high toward its rightful master. The rebounding Killing Curse hit Lord Voldemort, and his lifeless body hit the floor, his white hands then empty.
Honestly, Hermione knew Dobby was a lost case... nothing could have revived Dobby after the attack or she would have definitely helped Harry with Dobby considering she was the girl who started S.P.E.W(Society for the Elfish welfare) and fought for elf rights. There was nothing to be done at that point.
the malfoys hate the weasleys for two reasons : 1) their profound support for dumbledore order of the phoenix &and they were against dark lord ! 2) they unlike the malfoys were open to muggles being in the wizarding world ,they hated the fact that weasleys were friendly , supportive and loved the muggles .
In some parts of the saga, Draco even seems obsessed with Hermione. Even though he considers Muggle-borns to be inferior, he hasn't ever picked on one other than Hermione.
The injury was caused by Snape's Sectumsempra spell in order to stop the Death Eaters from hurting George (who he thought was Harry) and Lupin, but missed and hit George. Hermione and Kingsley then arrived, both unharmed, followed by Arthur and Fred Weasley, both concerned for George.
There is likely a good reason that the Sectumsempra is not an unforgivable curse. It's mostly because Sectumsempra is Snape's personal curse that he created. It is not a widely known or used spell, and it is one that he kept secret — which means it can't be added to the list since no one really knows about it.
What was Snape's reaction to Harry using Sectumsempra?
Later that night, after Snape killed Dumbledore, Harry attempted this curse against him multiple times, only for Snape to block it repeatedly and angrily reveal to Harry that he was its inventor.
