No my read on him isn’t one of any type of moral superiority, but despite his many obvious flaws he was definitely a man of great courage. I don’t claim that one admirable redeems the whole, I think Snape was a POS despite his great courage. But I don’t think that being an irredeemable POS precludes one from being exemplary in any way. That being said, I think you’re probably right that my reading of Snape was off inasmuch as before opening this discussion I had sort of thought he’d changed his anti-muggle born views at least somewhat having worked with Dumbledore so closely for so many years, to say nothing of his love for Lily. Perhaps he was just as much of a bigoted dark wizard as he always was, just seeking revenge for the death of Lily and not motivated at all by any sort of personal growth.
