I had a thought about the killing thing. Vader was not able to kill his son he'd never met, out of love. So would he be able to kill his wife??? I dunno.
Luke interpreted it as Vader being unable to kill him but I think Luke was wrong- he also thought Vader would not hand him over to the Emperor.
It was not until that very last sequence with Vader did Luke's idea pull off. I think beofre that point Vader had no beef with killing Luke if he had to.

TFN have revealed how Padme will die in Episode 3. Anakin will "Force Choke" her by accident and when Obi-Wan & Anakin duel. Padme will die giving birth to the children.
Luke 'felt' there was still good in him. That he couldn't put himself to killing Luke. The fact that Vader killed Palpy seems to confirm Luke's sense.
'You insights serve you well, Luke.'
Because he thought Vader did not kill him on ESB because he felt for his son. I do not think that is so for a moment, because by the same logic Luke thought Vader would not hand him over to the Emperor, and Luke was WRONG.
I believe no spark of anything in Vader was awakened until that final moment. Before that point, Vader was perfectly ready to kill Luke if he had to.

I do believe that in ESB is was merely for recruitment, but in ROTJ, after the talk on Endor, I think Vader felt something different. You can see it in his body language, he's really torn. I think he did want to train Luke because it was his son, but I don't think he had any intention of giving up being Sith until the end of ROTJ. AND WHAT ARE ANAKIN'S LAST WORDS?!
"You were right about me, tell your sister you were right". So OBVIOUSLY Luke isn't wrong if Anakin told him how he felt.
I think Luke stired up the conflict he says he feels in Vader, but I also belive the fact that Luke "escaped" him on Bespin got to him as well.
But he taunted Luke to fight him in ROTJ so................
Yeah, but didn't he stir that feeling on Cloud City? I think he did. After all, he didn't go and choke Piett after the Falcon's escape. The faces of the officers made clear that was something like a first.
one can only speculate the thoughts of Vader at the end of ESB, but the fact is Vader failed to do what he told the Emp he would do.
"he will join us or die". well neither happened so maybe Vader was concerned about the Emperors reaction to Vaders "failure"
Vader always wanted Luke as his apprentice, getting him in the same vicinity as Palaptine was mainly so they could gang up on and kick his @$$. Everything he told the Emperor was just to stall to give Vader enough time to turn Luke himself. Its the basic Sith mentality that Lucas has spoken of in interviews and commentaries. I don't think it was until ROTJ that he actually started to want Luke around as his SON as opposed to a tool to seize supremecy from Sidious.
As for Piett, he was just a really good and loyal officer, he respected Vader where as the others always sort of view him as an oddity. Like the first guy Vader choked, he was an arrogant little prick who tried to tell Vader what was what so he got choked. Vader did warn Piett "do not fail me again, ADMIRAL". So I'm sure he would have had choked him had he failed again.
