Well he would have been excommunicated form the Jedi for marrying Padme. It's not like he could hand in his light sabre and call it a day. He's far too powerful to be allowed to run lose without any guiding principles. The Sith is likely to recuit him if he doesn't spontaneously erect his own sith chapter... Life imprisonment, death or some drug that that purges his metaclorians... Wait? That sounds familiar?
Frankly that sort of Scandal would get Padme kicked out of office.
Skywalker was a bad, bad man.
