Dexter

I have just recently started watching Dexter, that show about the serial killer who only kills bad people and works as a forensics expert for the Miami police. It's such an intense show that makes me grossed out and intrigued at so many instances. The amount of blood and dismembered body parts on that show is disturbing, only I'm not fully disturbed yet. Have I become desensitized? Is this what society does to people? Have we been so tainted by the media that we watch shows about serial killers and actually enjoy them?
Anyways, that wasn't really what I wanted to talk about most is how the character always feels so disconnected from people. He goes through life pretending to be sane and normal, despite harbouring his dark passenger. Dexter is pretty sure that he doesn't feel most emotions that other people do, but he is able to still pass it off so well. I sometimes wonder if I was merely conditioned to act the way I do and if I'm really like Dexter, just trying to pretend and be as "human" as I can be. What a scary thought.
