... George Lucas explained the personal level through a type of pop-Buddhism:

“[Skywalker-father] turns into Darth Vader because he gets attached to things. He can’t let go of his mother; he can’t let go of his girlfriend. He can’t let go of things. It makes you greedy. And when you’re greedy, you are on the path to the dark side, because you fear you’re going to lose things.”

the parallel political question: How did the Republic turn into the Empire, or, more precisely, how does a democracy become a dictatorship? Lucas explained that it isn’t that the Empire conquered the Republic, but that the Republic became the Empire. “One day, Princess Leia and her friends woke up and said, ‘This isn’t the Republic anymore, it’s the Empire. We are the bad guys.’ [... Star Wars'] key insight [is] that “we are the bad guys,” that the Empire emerges through the very way we, the “good guys,” fight the enemy out there.”
