I suppose I just never saw Vader as attempting to reach out to others or longing for human contact. He seems to isolate himself from humanity, such as when he is in his meditation chamber in ESB and does not reach out to the flawed humans (but not monsters) that his officers are. More than anything, I get the impression that Vader sees himself as a monster. Having read that section, I'm glad Lucas chose to go the way he did. For me, Anakin fully believing in the Jedi's betrayal and turning solely because of political reasons seems a touch disconnected from ROTJ. In particular, I think back to his line of "Obi-Wan once thought as you do" where he does not seem to wholly regard Obi-Wan as a traitor. Despite all that has happened, I think that Anakin recognizes that the Jedi did not turn against the Republic, per se, but that they were a threat to the Empire. The way the movie plays out, he rationalizes their destruction as being for the good of the galaxy and looks at Mace's refusal to simply arrest Palpatine as a pivot point. The original turn also, I think, does not emphasize Anakin's attachment enough which was heavily stressed throughout TPM (the council chamber) and AOTC (his mother's death and the discussion with Padme of attachment). It also ties into the temptation of Luke better, I think. Also, I think I should just admit by bias upfront but...I have a few gripes with zombie in that, while he's entitled to his own opinion, I don't trust his editing and would really have to see the sources of his arguments. In particular, he excised portions of Lucas's 1988 Berne convention speech that I, personally, think renders his arguments moot. But that's a discussion for another time I suppose.
