As someone says in another franchise, only his body was in death. He, Skywalker, was not in death. He might have died, but at the very least he didn't stay dead.
I regret the use of the term "Force Ghost." It was casual. In my defense, I can only say that I was trying to keep this from becoming a chore. Anakin isn't a ghost. He is a luminous being, fully intact--and fully restored, in fact, to judge from the retooled ending of ROTJ.
You're looking at this much too conventionally. You must--what the hell? I'm in a quoting mood: You must unlearn what you have learned. :yoda:
2) I never said everything he did was heroic, only that he was the hero. And he was: Anakin Skywalker, who was, for a time, known as Darth Vader, is the hero. Saving Naboo royalty, destroying Death Donuts, rescuing various important individuals, serving the Republic, saving Luke, balancing the Force. He did all that. It says so, in the books, the scripts, the movies, the comics, the guides to this, that, and the other. Not sure about Wookiepedia, though... :scratchchin:
3) The Rebellion was insignificant. So was the Empire. You'll recall what Darth Vader said about the Death Star, which stood for the Empire: "Don't be too proud of this technological terror you've constructed. The ability to destroy a planet is insignificant next to the power of the Force." That was what was important, and what it all came down to: The Force. So, trying to stomp out the Rebellion and helping Obi-Wan become a luminous being, are not terribly important things, and, considering he was sworn to serve the Emperor, completely in the line of duty, and reasonably done.
