List of Dexter characters
At first, Harry attempted to manage Dexter's violent urges by only allowing him to kill animals, but he eventually came to the conclusion that Dexter's pathology could not be repressed, only controlled: Harry decided to train the boy as a vigilante, to hunt and kill murderers without leaving any clues. Dexter prized these lessons as a means to fulfill his desires with his father's approval, dubbing them the "Code of Harry". Harry's relationship with his biological daughter Debra, meanwhile, was more complicated. She craved her father's approval, but felt that he favored Dexter.
