Dexter Season 5 - Conscience or rage ?

Dexter had me going through 4 seasons without stopping.The idea that you could empathise with a serial killer is not conceivable, if you view it from a third person's point of view(victim or someone close to the victim) or as most  police procedurals do from cops' point of view.Cops point of view tends to be favorite because if you view the killer through the law enforcer's  eyes you can understand the killer not too deeply but just his twisted motives and the cleverness of the cops in bringing the killer down..Dexter differs by giving a first person point of view.Dexter Morgan is a blood spatter analyst for the miami PD who moonlights as a serial killer whose  victims  are murderers who have escaped conviction or ironically serial killers who were not caught or noticed.If you consider his acts he is a vigilante like batman which was brilliantly metaphored in one of his episodes where he considers a comic based on him,But what sets dexter apart is he does those murders because he feels a need ,a primal need that he needs to satisfy.Why does he choose his victims as murderers? partly because his adopted father told him to and because they wont be missed by the society.Dexter as a part of his cover dates and latter marries Rita,a divorcee with 2 kids.Dexter who has an emotionally empty core or no feelings, starts to have them once he connects with Rita and the kids(Dexter adores kids and hates pedophiles ,which is deadly for the pedophiles in the literal sense)which gets him wondering about responsibilities about what  would happen if he was discovered not for himself but for the family.It is at this point Rita is murdered by a serial killer(trinity) whom dexter was trying to model himself on,a family man and a serial killer.Though Dexter realizes  the facade about the Happy Family of trinity and kills trinity ,it was not without consequences,It caused him rita ,it orphaned his kids and it stopped his conscience from reaching a full moon?.It is with this premise the season5  starts with aptly put tagline.
