Snape was normally a very calm and reserved person, but he possessed a brutal temper that would infrequently get the better of him. He would react violently if he thought he was being pitied, underestimated or especially if he was being viewed as a coward. The most climactic episode where he lost his temper was in his famous duel with Harry Potter, where he turned furious and explosive when Harry used his own spells, that is to say, spells that he personally created against him, just like James Potter would. This gave way to pride, as he freely described himself as the Half-Blood Prince.Snape was, finally, an enormously brave man, throughout the course of the series, Snape puts himself in unimaginable danger every day of his life, in his efforts to protect Harry from any harm that came his way, he even protected Harry, Ron and Hermione from a werewolf by willingly acting as a human shield for the trio, risking extreme physical harm to his own body. Snape was a man who possessed a deep capacity for love. Everything that he did in the latter part of his life was motivated by his devotion to Lily Evans, who he loved unconditionally. He was one of Dumbledore's most reliable allies and in his role as a double agent, took great personal risk in ensuring Harry's safety at the hands of Lord Voldemort. Snape and Harry had a very complicated relationship, as Snape viewed Harry as an eternal reminder that his childhood bully married the love of his life and that Lily had died. However, he simultaneously saw Harry as the last reminder of Lily he had left, and as such, he vowed to protect Harry at all costs since Lily died protecting him, although his hatred of James lead to him singling out Harry and his friends the most during class. Harry, on the other hand, consistently saw Snape as a nuisance and frequently suspected that Snape was evil as he was a former Death Eater as well as his treatment of the students. Harry's suspicions of Snape allegedly were confirmed when Snape killed Dumbledore, after which Harry's dislike towards Snape turned into pure hatred, with Harry referring to Snape as a "traitor" and a "coward". It isn't until after Snape died that Harry learned the truth about the professor and the sheer lengths that he had gone to in order to protect Harry. After Voldemort's defeat, Harry made sure to make Snape's real nature be known to the world and even named his son 'Severus' in honor of Snape, whom he referred as "the bravest man he knew". "You dare use my own spells against me, Potter? Yes. I'm the Half-Blood Prince."
