Harry Potter: Sirius, when I was… When I saw Mr. Weasley attacked, I wasn’t just watching. I was the snake. And afterwards, in Dumbledore’s office… there was a moment when I wanted to… This connection between me and Voldemort. What if the reason for it is that I am becoming more like him? I just feel so angry all the time. And what if, after everything that I’ve been through… something’s gone wrong inside me? What if I’m becoming bad?
Sirius Black: I want you to listen to me very carefully, Harry. You’re not a bad person. You’re a very good person who bad things have happened to. You understand? Besides, the world isn’t split into good people and Death Eaters. We’ve all got both light and dark inside of us. What matters is the part we choose to act on. That’s who we really are.
