Originally posted by queeqNo, being destined to be the Chosen One earns him the title. However Anakin did the hard work too. He had to resist the darkside alot more often and on a completely different level than Luke. He was around it all the time, he was surrounded by people that were jealous of him and disliked him because of his power, to include a master Councilman or two. He had the shitty childhood and background to make him join the darkside long before he did, but he resisted all the while.
So tunring against and killing your family, losing wife and kids, hurting your son and turning on your master earns one the title of Chosen One??? That's very odd....Yes, Anakin suffered more. But Luke resisted the Dark Side twice, decided to risk his life to save his father who'd everyone had given up on, and risked his own life.... I call that doing all the hard work. Vader just followed his own desires until the love of his son made him turn.
And rather than "risking" his life, he gave his life to save his son and fulfill the prophecy. He turned on everything he believed in so he could have the chance to save the one person who showed him unconditional love. Of course that was manipulated by someone who played the ENTIRE JEDI ORDER, so yea, I'd say Anakin did a lot of the hard work and has a firm grip on the title Chosen One.
And no, the prophecy was not misread. GL stated that Anakin/Vader was the chosen one and did in fact fulfill the prophecy when he killed Palpatine. EP3 - special features - The Chosen One; as well as ROTS commentary.
