I can only feel sorrow for Draco. He was a slave during all those years! When you are born in a good family it is very easy to be a good person, cause it is what you have learnt during all your life. Draco was the son of the most coward character in the books, Lucius (with Petegrew), and a woman completely controlled by her husband. I always felt he wasnt that bad at all, but everything was much more difficult for him, and nobody ever tried to understand that, they only judged him since the first day without looking any deeper. Poor boy...
