He can't. He's all in for fascism. There's no going back to the shadows for him, he'll always be known as a Nazi oligarch. He said he would be going to jail if Trump didn't win. We know he's got ties with Putin so he might be being blackmailed into being the bad guy [not that he was good before, but at least he l wasn't toppling democracies before].
Nah. He has no interest in fascism. Fascism would hurt his bottom line immensely. He just tries to use his government position to give his companies, and by extent himself, more money.
The dude is motivated by money, not morals or his political compass.
