I think there is a whole lot more to be revealed about the origins of Trump as a 'serious' political candidate, and I think Russia features very heavily in that part of the story.
In terms of his private life, being nominated by the GOP and subsequently elected in 2016 was the WORST thing that could have happened to Trump as it opened him up to levels of scrutiny beyond anything he'd ever experienced before. It exposed his whole empire as a disgustingly corrupt organisation, and the reputational damage to many who have been associated with him and his companies is wide reaching.
I hope he does go to prison. I won't hold my breath.
