i mean, we've all seen return of the jedi. sure, luke is victorious. but i wonder, did vader just let him win? i mean vader didn't seem to be fighting at 100% on that one. he was just going through the motions, i guess. he tried to get hiss son to join him so that they could overthrow the emperor. luke wouldn't do it. so, vader takes him to the emperor so that he could turn him. vader didn't want to kill his own son. maybe vader just wanted luke to kill him so that he would survive and turn to the dark side. but then luke wouldn't even do that. tahts when the emperor stands up and starts to kill luke. and of course vader kills the emperor to prevent his sons death. maybe vader just threw that fight to save his son. know what i mean?
