How we cite our quotes: All quotations are from Harry Potter and the Prisoner of Azkaban.
Quote #4
MALFOY: Wait until Father hears Dumbledore's got this oaf teaching classes.
Malfoy is a jerk through and through. He seems to dislike Hagrid just because he's a friend of Harry's. And Malfoy will take any opportunity to hurt Harry, even if it means hurting his friends.
Quote #5
HARRY: He was their friend and he betrayed them. He was their friend! I hope he finds me. Because when he does, I'm gonna be ready! When he does, I'm gonna kill him!
Once again, we see Harry willing to commit an act of revenge against someone who hurt his parents. How does this make Harry any different from the person he fears Sirius Black to be?
