AM-Guard: Lucas is welcome to say whatever he likes, but I also believe that Peter Parker is Spider-man, Bruce Wayne is Batman, and Anakin Skywalker is Darth Vader. A lot of people get bolder and more aggressive when given the comfort of a mask.
And man, if you could take the good things you've done and declare that THOSE things are done by you, whereas the evil things you did were actually done by another person, you could get off the hook for, well, anything, in Lucas-land.
"Yes, right up until I killed the kittens and set fire to the orphanage, I was me. But when I did that, I became Darth Corrigible, so all of that stuff -- the murder, the arson, the destruction of entire worlds -- all of that can be blamed on him. I'm back to being me, though, now, so no worries."
If only Shakespeare had done it like that:
Hamlet: My blade twists sharp and lively in my hand,
Which trembles, womanish, before the deed,
Minerva's wit and Hermes' speed command,
But 'tis no longer my will thou willst heed.
Thine former owner Hamlet stands here dead,
And Darth Convenience guides the blade instead!
(Darth Convenience kills Claudius)
