Dexter Morgan

Dexter Morgan is the main protagonist of the Dexter television series. Morgan is a serial killer who only kills people who themselves are murderers. He is portrayed by Michael C. Hall, who previously received critical acclaim for his role as David Fisher on HBO's Six Feet Under.

He considers himself detached from humanity and often refers to "humans" as if he was a different creature. He finds children interesting more than the adults, and often targets killers who prey on children. He is also obsessed with routines and rituals. Moreover, he is very intelligent, observant and intuitive: being able to reconstitute any kind of crime scene, to manipulate evidences on the scenes of his murder to divert suspicions away from him, and to skillfully manipulate people. However, he tends to misinterpret elements in his investigations that can lead to disastrous mistakes.

Dexter has no interest in romance, despite being married to Rita (which, according to him, is a disguise). He witnessed his mother being killed with a chainsaw, by his brother, who also grew up to be a serial killer.

It was Harry Morgan who taught him the moral code stating that "It's okay to kill people who themselves are murderers.".
