That's a good question...if he had survived, I would probably not be so protective of him. I still do not believe that he was evil, not even when he was an active Death Eater. I can, however, make allowances for the path a neglected and maligned young Snape took, as he had redeemed himself by the life he led after defecting from Voldemort. Had he survived, I fully expect that he would not have been lauded by Harry and the other Order members. I will forever be sympathetic to his early struggles, to his latter struggles, for his whole life was patently unfair.
