I see a connection between Malfoy and Captain Ahab. Harry is Malfoys white whale. Harry is alot more powerful than Malfoy. In this way he's almost symbolic of a force of nature and the white whale. And one message of Moby Dick was that when you try to control or destroy nature you will only destroy yourself. Malfoy has proven this on the Hogwarts train at the end of GoF and at the end of OoP. I think this maybe the reason that Dumbledore didn't try to kill Voldy at the ministry. JKR said that Dumbledore said that he wasn't trying to kill Voldy because "there are other ways of destroying a man..." but there was also another reason that DD didn't try to kill Voldy. Even Dumbledore said, at the beginning of book one, that Voldy was more powerful than he was. He probably knew that he would only get himself killed by trying to kill Voldy.

Do you guys see a similarity between Malfoy and Captain Ahab, or anyone else and another character from a different story?
