Also, Robocop is a sci-fi version of Jesus Christ. Murphy's death at the middle part of the film is quite similar to the crucifixtion of Christ. The blasting off of his hand by Boddicker represents being nailed to the cross. The severed right arm represents the bairing of the cross. Being hammedred by the shotguns is Murpghy being whipped (notice the laceration during the ER scene). Finally, the gunshot to Murphy's head is his crown of thorns.
Robocop is one giant religious allegory, and notice the director of film, Paul Verhoven, has a history of making films that have a strong sense of humanity and Christianity.
Dick Jones is Robocop's version of Satan and the Old Man/CEO is God. Notice that Jones is driven by pride and jealousy towards Bob Morton, a common man in OCP. The end of the film is similar to the biblical fall of Satan in which he, or in this case Jones, rebells against God, or the old man, and is stripped of power and thrown out of Heaven, or OCP, and falls to the earth.
