[Star Wars] Darth Vader survives the Battle of Endor with Luke. What are the options for Vader's future?

What would the former Sith do with his time?

Probably help his son bring down the remnants of the Empire. As the former second in command of the Empire Vader might even be able to command the remaining Imperials to surrender to the Rebel Alliance. After that, Vader probably shows Luke all the surviving Jedi lore and artifacts to help him rebuild the Order. Of course this is all assuming the Rebels don't try to execute Vader on the spot. Luke would probably be able to dissuade them though.
