Severus Snape is a character in the Harry Potter series by J.K Rowling.
Professor Severus Snape (9 January 1960 – 2 May 1998) was a half-blood wizard who was the son of the witch Eileen Snape (née Prince) and Muggle Tobias Snape. During his lifetime, Severus Snape was Potions master (1981–1996), Defence Against the Dark Arts professor (1996–1997), and Headmaster (1997–1998) of Hogwarts School of Witchcraft and Wizardry (which he attended as a student from 1971 until 1978). He was also member of the Order of the Phoenix and played a very important role in both of the Wizarding Wars against Lord Voldemort.

Snape's friendship with Lily Evans was probably the only meaningful relationship he ever had. He first met Lily at a very young age, recognising her as a witch one day as she and her sister Petunia played in the park near his house. Longing to escape his humiliating home life, Snape immediately sought to make her his friend. Despite the fact that Lily came from a Muggle family, he never truly saw her as being one of them because he was so smitten with her. In 1971, the two of them were accepted into Hogwarts School of Witchcraft and Wizardry and continued a close friendship up until around their fifth year, despite being sorted into different houses.
During this time, Snape began hanging out with people who embraced sadistic magic and pure-blood supremacy, which put a huge strain on their friendship. Lily was offended by many of the views that Snape was beginning to adopt and disliked the qualities that his new cohorts were bringing out in him. Given time over again, Snape would never have done many of the things he did, but at the time he did not truly understand her aversion. He was so insecure and blinded by his attraction to the Dark side that he imagined she would find it impressive if he became a real Death Eater. Ironically, Lily might have grown to love Snape romantically (she certainly loved him as a friend) if he had not loved Dark Magic so much, and been drawn to such loathsome people and acts, yet it was Snape's desire for Lily's admiration that drew him to the dark arts in the first place. When Snape called Lily a "Mudblood" in a fit of anger and humiliation, it was the last straw for Lily. When she later asked him if he still intended to become a Death Eater and he did not deny it, she severed all ties with him, despite Snape's profuse apologies.
When Snape overheard the Prophecy, he immediately relayed its contents to the Dark Lord, not knowing that it would have anything to do with Lily. Upon discovering that Lord Voldemort was planning on targeting the Potter family, Snape pleaded with him to spare Lily in exchange for her husband and son. He later appealed to Albus Dumbledore, asking him to do everything in his power to protect Lily and the rest of her family, if he had to.
Snape was so devastated by Lily's death and ridden with guilt over the circumstances that he wished he were dead as well. At Dumbledore's behest, he became committed to protecting her son Harry and assisting him in defeating the Dark Wizard. Indeed, Snape's Patronus was a doe, just like Lily's, because he loved her throughout his entire life. As Snape died, he asked Harry to look into his eyes; his last wish in his final moments was to die looking into the same green eyes that reminded him so much of Lily.
From the day Harry set foot in Hogwarts, he and Snape loathed each other. Despite the fact that Snape was committed to honouring Lily's sacrifice, he could not bring himself to judge the boy objectively because of the connection to James Potter, who bullied him in his school days. Indeed, Snape was filled with nothing but contempt and bitterness towards Harry, who simultaneously reminded him of both Lily and James. Harry served as living proof of the fact that Lily had given her love to someone else, and Snape wasted no time in comparing him continually with his father.
During Harry's time at Hogwarts, Snape treated Harry viciously, both in class and out. He frequently derided the boy's abilities, bullied him in class and punished him whenever possible. He was also resentful and even somewhat envious of Harry's popularity, which he also equated with Harry's father. Although Snape threatened to have Harry expelled more than once, he never attempted to follow through — presumably because it would have led to Harry losing the protection surrounding him. However, never did he forget that Harry was also Lily's child, and much beyond bureaucratic rules, this led him to put the boy's safety in the most critical situation. When he learned that Dumbledore had intended for Harry to die all along, Severus remained horrified, seeing it as a calculated betrayal of Lily's memory.
When Harry helped Sirius Black escape, their relationship went under further strain, since Snape believed at that time that Sirius betrayed Lily to Voldemort whereas Harry had learned of his innocence, although Snape continued to put Harry's safety first. During the brief period in which Snape gave private Occlumency lessons, Snape relished in forcing Harry to relive his worst memories. During the early years, Harry associated Snape with his abusive and bullying ways but when Sirius died, Harry took savage pleasure in blaming Snape for having taunted Sirius about being useless, causing him to leave his hiding place and join the battle. Though Snape came to the aid of the Order as swiftly as possible, Harry blamed Snape mainly to ease his own guilty conscience about the entire incident. However, this was nothing in comparison to the retroactive rage Harry felt upon finding out that Snape was the one who relayed the Prophecy to Lord Voldemort, causing him to hunt down Harry and his family. When he later murdered Dumbledore, the hatred between them was sealed almost as personally as between Harry and Voldemort.
Only once did Snape ever truly see him as Lily's son, and that was in the moments right before he died. Following this, Harry was given access to all of Snape's concealed memories, which brought the former teacher's true intentions to light. When Harry discovered the love Snape had for his mother and the constant danger he put himself in to ensure his safety, his opinion of him changed completely. By adulthood, all of Harry's hatred of Snape seem vanished and looks as though he never harbour it. This can be seen through his request that a portrait of Snape be hung in the Headmaster's office at Hogwarts, which was not done immediately after Snape's death since he had abandoned his post. Furthermore, Harry gave his youngest son the name "Albus Severus", and told him that his Slytherin namesake was "the bravest man I ever knew."
Severus Snape was the Potions Master during most of Hermione's time at Hogwarts. He was also the Head of Slytherin House, and tended to openly show preferential treatment for the students of his own house, while being quick to criticise and deduct points from Gryffindor students. He was particularly unpleasant towards the trio, and regularly punished and verbally assaulted Harry and Ron for their poor to mediocre performances in his class. He could not do the same to Hermione, as she was the best student in the year and instead mocked her for things like being an "insufferable know-it-all," once even snidely insulting the size of Hermione's teeth. Despite his pre-existing dislike for Gryffindor, Snape's treatment of Hermione likely had more to do with her close friendship with Harry. Despite this, Hermione was still seen to defend Snape on occasion when Harry and Ron blamed him for evil deeds which occurred in Hogwarts, like setting the troll in the dungeon and trying to steal the Philosopher's Stone in Harry's first year. After Dumbledore's Death, she like many, believed that Snape was a coward who killed a man who trusted him more than anyone. It is unknown exactly how she reacted to learning of Snape's true motives and allegiance, but given her personality, it is highly likely that she came to both forgive her former Professor's cruelty, and even admire him for his bravery.
