JKs Meinung darüber, ob sie findet, dass snape ein held ist.

Yes, I do; though a very flawed hero.
An anti-hero, perhaps.
He is not a particularly likeable man in many ways.
He remains rather cruel, a bully, riddled with bitterness and insecurity - and yet he loved,
and showed loyalty to that love and, ultimately, laid down his life because of it.
That's pretty heroic!

"After all this time?"
"Always!"
