I agree with SOME of what you say ShoppingMaul. Not really on Luke but I like your points about how RotJ treats the Dark side of the force. I hate the idea that losing your temper and being angry is what makes you permanently turn to the dark side. To me, the dark side is a immoral use of power that is tempting to someone who wishes to abuse such power. It actually seemed like a constant moral challenge. But just because you resist giving into anger, you’re safe from the dark side???
Also, where does anger begin and self-defence end? Why is Luke’s attempt to kill the Emperor somehow immoral yet Vader’s throwing the guy to his death somehow worthy of a spiritual pardon? If anything Vader’s reaction is more selfish.
Clearly I’m not Jedi material!
