Lucas ensures the association between evil and machines in two crucial scenes: the scene with Ben and Luke in the Degabah System and the final scene of Return of the Jedi in the Emperor’s chambers. During his final visit to Yoda in the Degabah System, Luke learns that he must fight his evil father, Darth Vader, in order to secure the empire for the rebel forces. Luke fears being forced to kill his father, and he questions Ben if any good remains in his fatherÂ’s soul. Ben replies that Vader is more machine now than man. Lucas implies that Vader replaced his human characteristics with machinery and forfeited his good to evil in the process. Vader turned to the Dark Side, and Ben associates VaderÂ’s fall into evil with his identity as a cyborg. Finally, in the battle scene in the EmperorÂ’s chambers, Luke manages to revert his father from the Dark Side back to good. At VaderÂ’s catharsis, he asks Luke to remove the mask so Vader may look on his son with his own eyes. Luke realizes his father will die without the machine, but Vader insists on shedding the machine, along with his evil tendencies, to reveal his human face underneath. Once Vader has flouted evil, he rejects his mechanical parts to return to a more human-like character. Vader appears for the final time in Jedi as a ghost in human form without his black cape and machine which he has worn throughout the Trilogy. Vader emerges with Yoda and Ben, securing the idea that Vader has rejected evil and his identity as a cyborg to become human and allign himself with the altruistic rebels. Obviously, Lucas associates VaderÂ’s abandonment of evil with the elimination of the mechanical aspects of his identity.
