Dexter Morgan is a forensic analyst specializing in blood spatter who happens to be a unique serial killer devoted strictly to the murder of other killers. In large part because of his work with Miami Metro's homicide division, Dexter is able to come in contact with criminals who might avoid traditional justice through the legal system. Dexter prefers to make his kills in sterile, almost surgical environments, usually explaining to his victims why they are being killed before the moment of death. While Dexter does have a dry sense of humor, he generally handles himself in an almost emotionless manner, evaluating situations as objectively as possible.Background: Born in 1971, as a child Dexter witnessed the violent murder of his mother Laura Moser and several other drug addicts. Dexter and his brother Brian remained in the shipping container for days, surrounded by the carnage. The result was to create in Dexter a Dark Passenger, or psychopathic need to kill. This desire was ultimately channeled by his eventual adoptive father, Harry Morgan, the first person to find him at the scene of his mother's murder. Dexter eventually incorporated Harry's Code into his life. The Code consisted primarily of investigating kills carefully and making sure never to harm the innocent.
