I am taking the Saga seriously, though. I think it's a very important message to teach -- that's it's never too late to turn a new leaf, but that means owning up to what you've done and facing the consequences. Additionally, I think the point Lucas makes -- how difficult it is to believe in ourselves and how we often need someone else to see something worth saving -- is very relevant as well. Anakin is standing there happy and smiling for Luke. This is to show his son that he was right. As Anakin says -- Luke was right and Luke saved him through his faith. Anakin being there does nothing for Anakin himself. But it does give Luke peace of mind. And Anakin has realized that it's not all about him. And, I hate to say it, but in 1983 you certainly knew his history. This was a man who stood by and helped a bureaucrat as a planet of billions of civilians was destroyed, who committed genocide against a religious order that considered the early twenties "too old" to begin training. It doesn't take huge leaps of logic to see the implications of that.
