The difference is that overthrowing your master in the quest for power is still very much the Sith way and does not really violate his "values." It is the duty of the student to overthrow the teacher if they become weak enough to allow it, because only the strongest must rule. And each time his master foils him, he becomes smarter and better for next time. It's a mutual arrangement to keep them both at their best. When Vader tried to recruit Luke, it wasn't to free the galaxy. It was to rule it.
Again as per my theory, Vader's conscious motivation was his Sith values, but deep down he may have actually been motivated by feelings of regret, hatred for the Emperor, and longing for connection with his son. But he wouldn't acknowledge that even to himself. He mistakes his mask for his face.
Consciously deciding to save an old friend for the sake of their safety however doesn't match up with how I view his emotional situation.
Reading Lords of the Sith, I'd argue that Vader is having problems with this belief system.
It seems he wants the kill the emperor at some point, and the emperor has even encouraged this way of thinking, but Vader doesn't seem to be responding to it as he should.
He also gets easily distracted by thoughts of Ahsoka and Rex that give him pause. He even saved a random Twi'lek girl's life from being struck down by the Emperor. As brutal as he is there is obviously some things that hold him back and cause him confusion of himself.
On another note. Has anyone read the new Ahsoka novel yet?
