You mentioned "love" as a moral in the books -- while that moral is stated again and again, there's only a couple moments where it seems to win or even to drive major events. So far, hatred seems to win out, as practiced both by the bad guys and the good guys.

Unfortunately, that can happen. I was really hoping Fred and George's near-killing of Montague would be explored. But I think Harry is going to do a lot of questioning about how he acted in HBP, and hopefully will realize that nearly killing Draco did merit detention. (In fairness, he does say he deserves it, but he's still bitter about Quidditch.) Yet somehow, I hve a feeling that, and Hermione and Ron's actions, will be explored.

But I do think her books otherwise have good messages... I just disagree that the bad guys apparently "deserve it."
