You might be saying rn: "BuT hE wAs a gOod gUy"
But stfu
Snape bullied children, Neville specifically, to the point that he was their greatest fear (Prisoner of Azkaban)
Like he even criticized Hermione because she was a Muggle
He criticized Harry for being James' son
Before you say: "Oh, iT's beCauSe tHey reMinDed hIm oF lIlY"
Stfu again
Why would he bully people who reminded him of the girl he loved?
Oh wait, it wasn't love, it was OBSESSION
He had a Doe patronus, like Lily, which proves my point that he was obsessed with her
He even called her a MUDBLOOD
DAFUQ???
Conclusion: Fuck Snily, Jily better. Stay mad
