No, getting hit in his shoulder is irrelevant. The plan was to corner Luke and disarm him in order to persuade him to join him. He came to this point when the they moved to the very edge of that small platform. Regardless of Luke hitting his shoulder, there was no space and no reason to prolong the fight.

I don't think you've explored the emotional depth in this film to its full extent.

Further, the thing that really bothers me is that the screenwriter, actors, and other producers (like Kurtz) ... as well as the sound effects and visual effects people ... ALL understood these complexities and put them in the original film.

George Lucas obviously did not understand these complexities, and retroactively took them out of the film, turning scenes and dialogue from 3d to flat.
