There absolutely exist dictators that can kill people at their whims. The CCP comes to mind, so do Iran, North Korea and Hamas, but especially Putin's Russia where even being filthy rich does not protect you from falling out of windows.
And make no mistake, Trump and Erdogan want this power for themselves.
Meh. I think you underestimate the psychological difference between Putin level "I can kill you if you step out of line by pushing you out a window" vs ancient king level of "I can kill you at will because I am a god".
Pretty sure they actually have laws 'n shiet in China and North Korea.
Even (gasp!) Putler's Russia has laws and police, I've heard.
It's absolutely stunning what modern media has done to some people.
