So in preparation for OotP coming out, I'm re-reading the HP books from the beginning -- something I haven't done in quite a long while -- and noticing all kinds of things I hadn't seen before.
( Canon thump! )Before I re-read this bit of PS/SS I was almost prepared to buy into the idea that Draco's deepest desire is to please his father and make Lucius proud of him, and that all his detailed reports and attempts to assist his father in Dark activities were efforts toward that end. Now, however, I really begin to doubt that has anything to do with it.
I don't think Draco is afraid of Lucius at all, much less desperate to measure up to him. I think that he wants to be part of Lucius's Dark activities for the same reasons Dudley and his gang liked to beat up on Harry at school -- because terrorizing the weak and helpless is such a lark really, and why should Daddy have all the fun?
