How he died: Struck by a curse. Who killed him: Bellatrix Lestrange Why it is emotional: Sirius was the closest thing that Harry had to a parent he was actually aware of, and just as they are beginning to get to know one another and enjoy each other's company, he's inevitably taken away. Sirius loved Harry and Harry deserved to have that relationship with someone. Harry was adamant that Sirius was in trouble and without thinking, left Hogwarts to go to the Ministry of Magic to go to his Godfather's aid; however, it was Sirius who ended up saving Harry.
