This line by Vader in ROTJ has always puzzled me a bit. it has been sometimes addressed here and there in some thread but never had his own if I'm right. How do you guys interpreted it and interpret it now ? Did you pay attention to it or not really ? Does it simply mean that Vader is too addicted and engulfed in the Dark Side ways that he can't bring himself to come back, as I would suspect, or maybe that, at the time (1983), before the PT era, he was supposed to be afraid of the powers of the Emperor and that the Emperor could retaliate in some ways ? Does anyone knows if the DVD commentary gives further information on this ?
