I'm a librarian who loves anime, manga, and reading a wide variety of genres.
I don't think I really understood how horrible of a person and cop Harry was when I first listened to this. Dexter always presents him as a great guy, a cop who took a boy who turned out to be a monster into his home and helped make him less dangerous to the general populous by teaching him to control his urges and direct them solely at other monsters. Except Harry could have chosen to put Dexter in therapy and didn't. He just declared him unsalvageable, because of course cops know these things best.
