I'm really glad that Snape won
It was either him or Neville. I would have been alright with either of them winning. Neville was the unsung hero. The quiet boy who first stood up to the trio in PS and finally against Voldemort during the battle when everyone thought all was lost.
But Snape?? Yes he DEFINITELY deserved the win. Can you imagine how hard it must have been for him to 'act' as if he was back with Voldemort? How risky it was? Yes he had this Hate-Love...hate because Harry acted exactly like his father, but love at the same time because every time Snape looked into Harry's eyes, he saw Lily. The torture it must have been for him to secretly love someone who loved someone else and then to be the first person to find her dead. The agony to know that he wasn't able to save her. Yes he was the misunderstood "quiet" suffering hero.
