@Omar - Dexter quest is pretty simple - to lead a normal life. I think that's his main mission (while still indulging his psychopathic tendencies, of course). It's a really interesting take on a very stereotypical character type. I mean, how many movies and TV shows have there been about serial killers and their non-humanness? It's pretty ingenious to have found a way to make a serial killer someone you root for. By making him only kill bad people, it's like killing is a forgivable trait that he just happens to have.
