All was well

On a frosty night, in the dungeon of Hogwarts castle dwelled a sarcastic, bat-like potions master by the name of Severus Snape.

Most of us here love him, or at the very least, like him. Though I know I liked him from the very beginning when his sarcasm began to show, I also know many of his dedicated fans hated him at that time - for bullying Harry.
But, we ask ourselves, why did his fans forgive and love him? This question is rather simple and the answer is without a doubt. Because of his unconditional love for Lily. And, we also ask ourselves, why do we find his love for Lily touching? Because...

We all know who they are. We even seen them in Snape's
memory. They were one of the coolest kids at Hogwarts, all though they were a bit mean.
We all know Moony (Professor Lupin) was a werewolf and when he transformed he'd go to the Shreiking Shack were he'd endured very painful transformations.
We also know that the other's instead of running away in terror thought it was cool and therefore turned into Animagus.
Remus Lupin as I said Moony the werewolf.
Sirius Black as Padfoot the dog (but bearike).
Peter Pettigrew as Wormtail the rat.
James Potter as Prongs the stag.
Together they make the four...
