I don't know if anyones read Return of The Jedi, but in it is a "scene" where the Force Ghost of Obi Wan is talking to Luke on Dagobah. Luke tells Obi Wan that he has felt good in Vader, and he thinks he can save him. Obi Wan tells Luke that he once thought Anakin could be redeemed, and they fought, and Anakin fell into a molten pit; obviously causing the mechanical limbs and respitory equipment.
