The feels

Eh he was bullied as a child, the girl he had a crush on for years and kinda was in love with ran off with his bully and got married, the bully became very successful, then he saves his life forcing Snape to owe him. Then they both die but of course they had a son, and what do ya know he's the chosen one that supposedly destroyed voldemort. He didnt, but then defeats him multiple times later and becomes a celebrity, making Snape even more spiteful. I'd be pretty grumpy too if I was snape.

Yes but he was a horrendous bully to their son, still obsessed about his mother years later, and was terrible enough to become a student's boggart.

True it still wasn't Harry's fault but he had some justification.

if snape was supposed to keep the role of a double agent he can't be nice to gryyfindors he had to be rude to them so the death eaters wouldn't get suspicous

but the fact that he liked a girl a decade after she died is obsessive

Also good points

Wait what? You go on loving people after they die... It wasn't some girl he has a crush on, she was a friend too
