Luther as an anti-hero

Lutrher is a DCI (Detective Cheif inspector) in the BBC crime drama "Luther". He is suicidal because he just runs straight into the line of fire and uses himself to tempt out the serial killers rather than make a tactical approce and capture them as a team. He makes many references to the devil, like when he insulted the female reporter and said that her phone number waas "666". Also he is socialising with Alice who is a serial killer to the extent that they are meating up and talking on the phone regularly through out each episode. He let the man fall and he punched his wife's boyfriend in the face. He is the complete opposite of Horatio in the way that he would rather get revenge on someone rather than convict them. Horatio wouldn't have let the guy fall he would have helped him up and arrested him but Luther punished him for the crime of kidnapping those girls by himself by letting him fall to his death.
