Funny thing, in the comics, he has gone back to Tatooine. And... Spoiler He slaughtered so many Sand People and ended up becoming a Legendary Dark God to them. Current Marvel Canon storytelling. It's just that despite the meme 'Annie no Like a sand?' nitpicking, he has gone back, and when he does have to go there (because the Emperor likes torturing him) makes everyone just as miserable as he is for being there. Especially Sand People. The edict came down loud and clear, make Vader 'not quite' Forced Unleashed power levels, but he can take on a Army alone. I have no issue with that either. He needed the redemption.
