Response to the ending of Blue Angel

I feel like the ending was anti climatic, the way nothing actually happens to professor Swenson or Angela and there isn't this great big dramatic ending. We addressed this in class and some students said it wasn't the ending they were expecting or hoping for. And quite frankly, me too, but at the same time I think this was the only way it could've ended. We have just been with Professor Swenson throughout the whole book. We, the readers knew more than the characters themselves, just by being in his thoughts we were the ones that knew his character the most. We almost felt closest to him as well, so even if we ourselves wouldn't do what he or Angela did, for some reason we or most of the readers would be upset if anything greater and awful would've happened to his character. And I believe that is because the writer Francine showed and brought us along with him and his most weird/ unacceptable thoughts that no one would ever actually say aloud that made us feel sympathy for him, even though we knew what he was doing was wrong.
