Luke a Jedi?

[Stealhead]

I always thought that Vader was Lukes ultimate test will he take the easy route and give in like his father or will he take the harder route and not.Obviously in Empire Luke took the hard route and in effect he attempted suicide(he could not have been sure of survival when he jumped to get a way from Vader) rather than the easy route of surrender.So to some extent at that moment he became a Jedi because of his choice at the most difficult moment when the easy route the dark side would have guaranteed survival and power he chose the Jedi path.

Then in Jedi The Emperor and Vader intent was to lore Luke with anger to the dark side and in the film it does seem at first that he is giving in but when he sees at last what Vader was and how he become that way he stopped his attack on Vader.This was so powerful a deed that it even broke Vader and he saved his son from death even though it cost him his live.That moment where Luke could have struck Vader down in anger was his ultimate test but he became a Jedi when he jumped away from Vader in Empire.

To me it is implied that once one becomes a Jedi they can still be tempted by the dark side at the same time one can become like Vader and deeply follow the dark side yet still redeem themselves to light by being selfless.
