Sorry I disagree. A code of conduct is very different from morality. Following a set of rules in order to avoid punishment isn't morality. It's just self preservation.
Dexter seeks gratification for his blood lust, and his stepdad pointed him in a direction that would allow him to do so without being caught (by teaching him how to cover his tracks).
His stepfather understood that it was only a matter of time before Dexter started killing people, and that left alone with his bloodlust he might not discriminate as to the victim. So he set up rules for his killing which satisfied Dexter's need to kill but also the stepdad's own ideas about justice. I'm sure he was frustrated as a cop watching guilty people go free, and turning Dexter loose upon them was a way for him to see his version of Justice done.
If his stepdad hadn't intervened, Dexter might just be another sociapathic murderer, killing at random or when he was annoyed by someone. But he's still just following a set of rules that allow him to gratify himself. There's no morality behind it.
As far as his Dad's code being all Dexter has, I don't think Dexter HAS anything except murder. The only topic that excites him is murder. When he was talking to his girlfriend in the car and was talking about cutting people up, THAT excited him. Nothing else interests him.
