okay well my opinion is long i think Snape was a good person and if he didn't call Lily a mudblood they could been happy together.Yes i do think Snape was much of a father figure to Harry always saving him as bitter and cold as Snape was he never showed it but he grew to Liebe him and see alot of Lily in him. So over all i think Snape was a good man and it could have worked out and he was Merida - Legende der Highlands and noble person for taking on the father figure to Harry for the Liebe of his life as much as he hated James.
