Sirius' death is the one scene that literally had me in tears. The fact that JK Rowling killed him off upset me terribly. See he wasn't supposed to die, he and Harry were supposed to live happily ever after as a family with Remus.
I saw those two men as the family he was denied as a child. He lost his parents as a baby thanks to Moldyvort and then was forced to live with a verbally abusive aunt and uncle who despised his very existence. Then to have to deal with a physically abusive cousin was more than he deserved.
