When one recalls that JK Rowling is in fact a woman, and as such, things such as honor, bravery and even heroism itself are somewhat out of her realm of understanding, you shouldn't be surprised when you don't find any real examples of these things in any of her books, even though the plot and story-line are actually fairly good. Though that sounds sexist I don't mean it to be, because I know, as a man I'll never be able to understand some of the things that women do, so I don't expect them to comprehend manly concepts.
