Dexter Season 08 Complete

Orphaned at the age of three by his mother's murder, Dexter Morgan is adopted by Miami police officer Harry Morgan and his wife Doris. After discovering young Dexter had been killing neighborhood pets for years, Harry tells Dexter he believes the need to kill "got into" him too early, and Dexter's need to kill will only grow. To keep Dexter from killing innocent people, Harry teaches him The Code:
Most importantly, Dexter must never get caught.
Dexter's victims must be killers themselves who have killed without justifiable cause and are likely to do so again.
Dexter must always be sure of his target's guilt, thus he frequently goes to great lengths to obtain undeniable proof of his victim's guilt.
