John expoundsa passage at the end of the film in which he says that he was chosen by God to punish those who have sinned.But I think he's an arrogant and forced their existence meaning, gluttony, greed, sloth, wrath, pride, lust, envy, the seven deadly SINS John took eight people to complete, additional one person was killed, it is in itself a belief is not the same with him, the film shows the depravity of human nature, the guilty will be punished, after such a killer to represent god punished, but he is not what the angel of god, in my eyes, he was just a killer experience defects, since he is not god's representative, he also have no power to decide life and death,He is just a man living in his own world, and the reason given by God is a reason for him to deceive himself. There is no sense in what he has done, let alone right or wrong.
