The greasy haired, hook nosed potions master in Harry Potter that "loathes"...mostly everything. Mysterious, and has a haunting past. Was a death
eater, but turned spy for Dumbledore
and the Order
Of the Pheonix.
In the sixth book, Snape
In the seventh book, Snape
shows Harry why he did it. Turns out he loved Harry's mother, Lily, and turned to Dumbledore
when he found out Voldemort was going to kill her (and her son and husband). When Dumbledore
has one year left to live

Dumbledore: But this
is touching Severus
, have you grown
to care for the boy, after all?
Snape: For him? Expecto Patronum!
(A silver doe patronus like Lily Potter's emits from Snape's wand.)
Dumbledore: After all this
Lily Potter: Does it make a difference, being Muggleborn?
Snape hesistated. His black eyes, eager in the greenish gloom moved over the pale face, the dark red hair.
Snape: No, It doesn't make any difference.
