But there was one emotion he could never keep entirely hidden: his bitter jealously and deep resentment of Harry's father. When Dumbledore decided Harry needed to learn
Severus Snape wanted to teach D.A.D.A. for years, but Albus Dumbledore denied him the job repeatedly, partly for fear of Snape straying back towards the darkness, and partly to keep him around for longer, given the curse on the position.
Here's the thing: Dumbledore knew that Snape was mean to the students, but the headmaster still allowed it. It's likely that he did this because he believed that his students needed life lessons, including how to deal with mean teachers.
Dumbledore was also aware that he wouldn't be alive for long because he had been cursed by the Horcrux ring. Instead of suffering a painful death, he urged Snape to end his misery.
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. "All the same, try.

Voldemort told Snape he had been a faithful servant, but that he had to regrettably kill him, as he mistakenly believed he was the master of the Elder Wand, as Snape had killed Albus Dumbledore, its former owner the year prior, during the Battle of the Astronomy Tower.
Gaunt's ring
After retrieving the ring Albus Dumbledore himself fell victim to a curse that, even when contained, would likely have killed him within the year. Once rendered defunct as a Horcrux, the stone was placed inside a Golden Snitch and left to Harry Potter in Dumbledore's will.
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.
A Professor at Hogwarts School of Witchcraft and Wizardry, Snape is hostile to Harry due to his resemblance to his father James Potter, who bullied Snape during their time together at Hogwarts.
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.
First, he needed to clear Hagrid's name when he turned out to be innocent of opening the Chamber of Secrets. Dumbledore wanted people (mainly the parents of students) to trust Hagrid again. The second reason is that Hagrid does possess the required knowledge. I still would have hired Grubbly-Plank, though.
Voldemort trusts Snape because he's good at his job as a double spy and as an Occlumens. Voldemort is so conceited that he probably just doesn't expect Snape could be a better Occlumens than he is a Legilimens.
Snape hated Neville because he was a daily reminder Lily Potter could have lived. Snape's guilt over his part in her being targeted by Voldemort in the first place was bad enough, but to see a living, breathing reminder that things could have played out differently even after that act made Snape particularly vicious.
The big “secret” about the Dumbeldore family that the title promises is actually an explanation of the last film's cliffhanger. Albus confirms to Creedence early on in the film that he is in fact a Dumbledore, quashing any rumor that Grindelwald had lied to the young boy in order to sway him to his movement.
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.
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.
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.
Defeating The Dark Lord with his signature spell
Disarming is about defence, not murder. Voldemort was a killer, Harry was not. It was an important distinction for Harry, who had learned so much about Voldemort and seen first-hand the ways in which they were similar.
He said, "According to Victorian flower language, asphodel is a type of lily meaning 'my regrets follow you to the grave' and wormwood means 'absence' and also typically symbolizes bitter sorrow." If you combined that, Snape's words mean "I bitterly regret Lily's death."
"The first thing Snape asks Harry is "Potter! What would I get if I added powdered root of asphodel to an infusion of wormwood?" According to Victorian Flower Language, asphodel is a type of lily meaning 'My regrets follow you to the grave' and wormwood means 'absence' and also typically symbolised bitter sorrow.
Severus Snape is one of the most divisive characters in the entire "Harry Potter" series. He was a double agent, so many character details were kept a secret. His mother was a witch and his father was a Muggle, leading to the moniker "The Half-Blood Prince."
