Vaders Suggestion

Why did the Emperor agree to Vaders suggestion off trying to turn Luke to the dark side. This must go against the "principals" of the siths.
(Always two there are, no more no less)

I think he was wanting Luke to replace Vader.

them being father and son might be a danger towards the emp himself

Which it evidently was in the end, maybe the Emperor thought the allure of the dark side would over-power any emotional links. Vader had many years of being Obi-Wan's padawan so was not molded exactly how the emporer may have wanted him, the Emporer could have taken Luke with his little training and used that to mold him how he wished, even using the destruction of his friends and eventually his own father to fuel his turn to the darkside.

Still they would make a huge treath towards himself.

yup, agree with Corran...
wasn't this in a thread a few months ago?

Vader wanting that so they could rule the galaxy as father and son
and the emperor wanted Luke 'cause he was "the rising star" of the dark side and Vader was too much machine to qualify as The Chosen One

No, I agree with Finti's basic point- the two of them out and out AGREEING to take on Luke seems absolutely ludicrous with the 'only two' rule. That they would actually want Luke for their own agendas fore the reasons you describe above is, of course, a given- but the two of them TALKING about it, knowing that one would have to bump off the other?

I used to think the rule of two had been dropped by the OT now the Jedi were gone, but GL's comments suggest otherwise so I leave this one rather fuzzy.

BTW, too much machine to be the Chosen One? WHy is that a problem?

and Vader was too much machine to qualify as The Chosen One

well, The Chosen One is Anakin, Vader isn't Anakin
Anakin = light side
vader = dark side

could be Palpa wanted to stop the prophecy of ever happening? Kick Vader while he had the chance

Vader IS the Chosen One, yerss, no matter which side of the Force he is on or how ever much you want to play into the split personality thing. The good person who is Anakin may no longer exist but he is still the same being and that being is the Chosen One.

more or less what Ush summed up there Yersie boy.

It's DOCTOR Yerssot for you.
I didn't spend six years in wacko school to be called boy, thank you very much

By the novelisation we know Vader had plans to overthrow the emperor, even thoug it is euish it is a thing the emperor must fear

the novel is NOT eu

yes it is, it claims Owen to be Obi wans brother which he aint.

all things said in the novel are canon, except from the things that contradict the movie directly

Time I reminded everyone again that, right or wrong, the novel isn't EU as it is not an orignal story, like EU has to be. All EU is non-canon but not all non-canon is EU.

Anyway, the novels live in that rather fuzzy 'semi-canon' area.

by only you

I doubt GL had thought of the only 2 sith lords idea at the time of ESB ... he only came up with that at the time of the PT ... therefore at the time of making ESB, the question of how there could be a third sith did not arise.
