Has anyone ever noticed how similar Luke Castellan and Anakin Skywalker are in terms of their transition from good to evil, from light into darkness? For example, in both cases they were corrupted by a purely evil entity that desired revenge against the forces of good(the Olympian gods and the Jedi knights) that they(Luke and Anakin) had chosen to ally themselves with. Also, both Luke and Anakin were angry and bitter and felt like their ally, or parent in Luke's case, owed them something. Kronos and the Emperor, aka Darth Sidious, aka Chancellor Palpatine, the evil entities I mentioned before, used that anger and bitterness and, once they had Luke and Anakin on their sides, their new servants' desire for vengeance to fuel their own plans for revenge against their enemies. However, I believe Luke is decidedly less weak-willed than Anakin, as it took Kronos more time to turn Luke evil than it took the Emperor to convert Anakin to the Dark Side.
But let's not forget the profound similarity between Luke Castellan and Anakin Skywalker- their transition back to good and subsequent deaths. For both of them, once they witnessed their evil masters hurting someone they cared about they were compelled to act out against them in defense of that person, sacrificing their own lives in the process. For Luke, that moment came when,under the control of Kronos, he knocked backwards hard enough to seriously injure her becuase she was fighting him, trying to get him to fight off Kronos' possesion. Once he realized what he had done he gained control of his body long enough to sacrifice himself and so prevnet Kronos from assuming his true form and destroying the world. For Anakin, as anyone who had seen Return of the Jedi knows, that moment was when, as Darth Vader, he watched the Emperor torture his son Luke( the Jedi,not the demigod) with Force lightning. In order to save him, he threw the Emperor down a deep shaft, which presumably killed him once he hit the bottom(physics,after all, applies to everyone, even crazy, evil, old emperors). However, the Emperor's Force lightning severelydamaged the delicate mechansims needed to keep Anakin alive, dooming him to a slow, painful death. In the end, both Luke Castellan and Anakin Skywalker died heroes, if only to those who had wittnessed their deaths.
Well, that's all for me! Hope I've given you something to htink about!
