Snape was born to Eileen Prince, a witch, and Tobias Snape, a Muggle, making him a half-blood (hence the name, "Half-Blood Prince"). This is rare for a Death Eater, as remarked in the last book, though Voldemort himself also had a Muggle father.
Severus Snape's nickname, the Half-Blood Prince, was a clever description of his half-blood lineage. Snape chose the name as a tribute to his mother and to distance himself from his muggle father, drawing an interesting parallel between this character and Lord Voldemort.
Why was Snape in Slytherin when he was half-blood?
Because Slytherin was NOT the house for ONLY pure-bloods. If that were the case, then Slytherin would NEVER have a full house. Look, Slytherin house IS willing to accept half bloods. There are even reports of rare muggle borns entering their house.
Why is it significant that Snape is the Half-Blood Prince?
He calls himself this because his mother's maiden name was Eileen Prince, and his father, Tobias Snape, was a muggle. Snape likes to use his mother's name as a way to reference his long line of wizard blood. This is one of the most significant similarities between Snape and Voldemort.

The fact Snape and Lily were only friends, and she only saw it as such, reveals a lot about his refusal to respect her boundaries. It seems his love was an ongoing obsession with her that lasted long after her death.
By Harry Potter and the Deathly Hallows, it's a stretch to call Draco a villain anymore. We just watched — or read — him struggle to reconcile his choices and morals in The Half-Blood Prince. He can no longer justify his actions, and is far more aware of the evil he was born and raised into.

Snape always wanted to be a Slytherin. For him, his genius and creativity wasn't about that nature per se, but what it could give him. A Ravenclaw learns for the sake of learning, for curiosity's sake. And while Snape had the potential for that, that's not how he applied himself.
However, there were a select few that had his trust, and whom he treated with respect. This included Bellatrix Lestrange and Severus Snape. No matter what Snape did as a spy, Voldemort never figured out he was not on the Dark Lord's side.

He is an exceptionally skilled wizard whose extremely cold and resentful exterior conceals deep emotions and anguish.
