Afterwards, Padme and Obi Wan, travels to Mustafar which consists of volcanoes and flowing lava to either help him or for Obi Wan to kill him. Padme and Vader has an intense conversation of Vader turning to the dark side, and that he is powerful and he can rule anything. Padme then realizes that she cant be with Vader because he is going down a path she cant follow because of what he's done and what he plans to do. Vader begins to start choke her and making her fall to the ground unconscious. Shortly after, Obi Wan and Vader has the most intensifying lightsaber battle, leaving Vaders legs and his left arm detached from his body. Obi Wan leaves him to die and his severed body catches on fire. Palpatine then comes to Vader's rescue, and he is then reconstructed into a black suit of armor. This shows that he lacks empathy, because he started to choke Padme, fighting with Obi Wan, killing everyone inside of the Jedi Temple and the sandpeople, and betraying the Jedis. According to Solomon (1989), "When the focus of life is on determining one's own needs and finding another who can fill those needs and wishes, any relationship is in danger of being flawed by narcissistic expectations. It is increasingly difficult for people to enter into loving relationships and to maintain them once they begin" (p. 4). For Anakin and Padme's relationship it was set to Anakin's own needs and wishes, to become powerful and to rule anything. Because of this, Padme left him due to the fact that he's going down a path she cannot follow.
