The reason to have courts at all is to have an alternative to violence to resolve conflicts of interest.
This is why black market negotiations are done featuring a lot of well-armed guys.
This is also why the public needs to be able to trust the courts are impartial.
This is why even the appearance of misconduct cannot be tolerated.
So at the time your goons kill their goons to resolve the dispute, kill the corrupt judge as well, because its his fault you had to resort to violence in the first place.
When McConnell blocked the confirmation of Garland to SCOTUS, he also blocked over a hundred federal bench appointments, so many, that the Federalist Society was struggling to find enough to fill the seats, so yes they were scraping the dregs at the bottom of the conservative barrel.

Curiously, in movements like the white Christian nationalist movement that had been commandeering the GOP since the 1970s (which is not to say they were much better before that), the shift from principle to personal loyalty results in brain drain, since competent officers with dissenting opinions are swapped out for incompetent ideologists. The German Reich also had to deal with this kind of problem.
