Somewhere in his twisted mind, Roberts know his legacy is ruined and he will go down as the head of the execution squad ending the experiment in democracy, a complete and total reversal of almost 250 years. He now owns it.
It all depends if Robert's view of the law wins. In a Christo fascist American authoritarian state he will be viewed as a hero. Schools will bear his name. Statues of him will be built. You get the picture. I am sure Roberts and his fellow justices want this future.
