The troubled Girl in 'Mother, Mine' was a killer, yet we as an audience felt sympathy for her, as she tried to find a mother figure to accept her. This got me thinking of other complex characters and the layers that create their deep personalities. I am currently watching the Showtime series 'Dexter', and was reminded of Michael C. Hall's lead role as the killer turned avenger by Susan's adoptee character.
Through the series, Dexters bond with his girlfriend Rita (original sought out as a disguise to hide Dexter's detached and monstrous true self) and her children grows stronger. Harry convinced Dexter that he was monster through his childhood. He made him feel damaged beyond repair. Dexter grows gradually more human through the series, and begins to ask himself whether he is destined to kill to keep his darkness at bay, or whether some day he can be rid of the dark passenger and live like a normal human.
With Dexters complex character comes various themes: Is there a dark passenger in all of us sitting dormant? Who deserves to live or die? How well do we know the ones close to us? We all have our secrets and Dexter's character really explores these key themes.
