Seriously! THIS is the guy you pull the trigger for! THIS is the guy you give up everything for! It's absolutely insane. They can see how he treats his subordinates and enablers -- all of them ultimately get thrown in the trash. And yet.
I struggle to think of examples of authoritarian slide where this hasn't happened. The specific form it takes - long knives, falling out of windows, etc. - varies, but the consolidation of power and petty retributions are common.
