(Sorry this took so long, I've been busy and tired. I'm currently tired, so forgive me if I meander.)

Hmm~ I was going to rebut that with a "But Luke gets the same injury Anakin did and gets a mechanical hand, and HE's good!" But the next time we see Luke, he's wearing black, and I was always put off by how he was suddenly all serious and vaguely creepy in the beginning of RotJ. It's been too long since I saw it to remember more details. Hmm. Anakin's prosthetic hand didn't really look very human-like, either, probably some clever ~symbolism~ that that's the point at which he starts sliding into "more machine than man" land. [Tangent: I just realized that the "more machine than man" line could be metaphorical in addition to literal-- that he shut down his emotions and such when Padmé died and became a tool to be used, basically programmed by the Emperor. *chinscratch* I have to think about that.] And since Luke's prosthetic is made to look like a human hand, he's refusing to let the mechanical aid compromise his ~humanity~.

Oh, boo, and to die redeemed Vader has Luke take off his helmet, which has his respirator. So he has Luke take him off life support to be good again. That's questionable. I can't remember the dialogue, though.

UGH UGH UGH DAMMIT DAMMIT DAMMIT! Avoid one fail, revel in the next. UGH!
