Originally Answered: Why did Dumbledore plead with Snape? Dumbledore knew Snape didn't want to kill him and was afraid that Snape would still refuse to do so, and would then be killed by his Unbreakable Vow.
By saying "Severus... please" Dumbledore was able to subtly signal to Snape that he was ready. Also, you have to remember that Snape was feeling slightly apprehensive about killing Dumbledore. So in a way, Dumbledore was actually pleading with Snape, only it was for the total opposite reason the Death Eaters though.
Yes, Dumbledore did ask Snape to kill him so Draco wouldn't. Dumbledore did indeed ask Snape to kill him, so that Draco wouldn't either succeed and maim his own soul, or more likely fail and be killed by the Dark Lord for his almost inevitable failure.
Dumbledore found out about Draco's task to kill him and so asked Snape to do it instead. Dumbledore learned he had only about a year left to live after he was cursed by Marvolo Gaunt's ring, and although Snape contained the curse, it would spread throughout his body and kill him.
“You disgust me,” said Dumbledore, and Harry had never heard so much contempt in his voice. Snape seemed to shrink a little, “You do not care, then, about the deaths of her husband and child? They can die, as long as you have what you want?” Snape said nothing, but merely looked up at Dumbledore.
After it was revealed that Dumbledore was devastated by the accidental death of his sister during a fight with Grindelwald and his brother, Aberforth, it became clear that Dumbledore's deepest desire, and regret, involved his family.
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.
Knowing that Snape has been on the Dumbledore's side for all seven of the Harry Potter books reveals him as an extremely brave man and a truly skilled spy. Snape has had to face and deceive the terrifying Lord Voldemort constantly.
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.
However, Draco was ordered by Voldemort to kill Dumbledore. Lestrange saw this as an opportunity to test Snape's loyalty and while making this vow to always watch over Draco, Lestrange forced Snape to agree to killing Dumbledore himself in case the youngster was unable to do so.
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.
He played the part of a loyal servant to Voldemort so well that Voldemort thought of Snape as his most loyal and capable servant. He regretted the (supposed) necessity of losing his (supposed) most valuable servant. He felt nothing for Snape as a person — the only person who mattered to him was himself.
Now, as firmly established, Snape was not the greatest fan of Harry, but that didn't mean that he ever stopped loving Lily. Dumbledore was surprised that Snape seemed to care for the boy. With a swish of his wand, Snape conjured up a Patronus – Lily's Patronus, a doe. 'Always,' he said.
Similarly to Harry, Snape's patronus represents a person. In the memories he gives Harry before his death, Snape shows Dumbledore his patronus, using the form to prove his love of Lily Potter, Harry's mother.
Despite Snape killing Dumbledore, it is learned that they had a special agreement for him to do so. When he died, it was revealed that his deep strong love for Lily Evans caused him to redeem himself, joining Dumbledore's cause for her protection (and, after her death, that of her son) from Lord Voldemort.
He doesn't trust Snape as Dumbledore does, but he believes that he can detect any disloyalty. Moreover, Voldemort regards Snape as highly intelligent and therefore ' as a true Slytherin ' a person whose top priority is to take care of himself. To his twisted mind, selfless equals stupid.
All lessons at Hogwarts were suspended and all examinations were postponed, every student (with the exception of those taken from school early and Draco Malfoy) was present, as were all Professors, excluding Severus Snape. Dress robes were worn.
He was the one who told Voldemort about it, and so when it became clear that it referred to a baby and that this baby was the son of James and Lily Potter, Snape knew about it first-hand.
Harry later discovered that Snape was once a Death Eater but had been vouched for by Dumbledore.
Verdict: Snape Is the Stronger Wizard
McGonagall is surprisingly skilled in the Dark Arts but not on the same level as Snape. She's also most likely incapable of casting the Killing Curse, which puts her at a disadvantage.
Albus Dumbledore
"Severus, please." Watching Snape kill the Hogwarts headmaster was gutting; finding out that Dumbledore "begging for his life" was actually begging Snape to kill him was a sad reminder of just how selfless this man was.
Author JK Rowling announced Albus Dumbledore was gay in 2007. It's known that he and Grindelwald were in a romantic relationship but it had never been explored in the previous Harry Potter films. Fantastic Beasts 3 might address the depth of their relationship.
Let's see: nitwit means a daft person, blubber means extra fat, oddment means a portion of cut-off fabric, and tweak means to slightly adjust something.
