In Revenge of the Sith the video game, there is an alternate ending mini-movie where Anakin kills Obi-Wan on Mustifar, then returns to visit Darth Sidious, who gives him (Anakin/Vader) the red lightsaber. But then, Anakin KILLS Sidious and says "The galaxy is MINE!" Its pretty cool! But it made me wonder: IF Anakin is sooo powerful - Sidious even told Yoda Vader was more powerful than the 2 of them - why is he [Anakin/Vader] so content being the Emperor's "B*tch"? Wouldn't you strike his old a*s down after he laughed as he told you your wife was dead? I would! But then again, we wouldn't have any movies' to "wonder" about!
