You know the difference? The American establishment has so much manipulative power and influence, they don't need to imprison and kill people directly that often. The control exerted by the oligarchy in the USA is that big, as has been seen in the last elections, that they were not afraid of being overruled. That changed with Trump, somewhat, and that's why the individuals freedoms being restricted, the social, economical, political and legal pressure on people having dissenting opinions being increased in the West also. There is a difference in quantity, not quality, in many "Western states".
But what's even more, the USA with their "Liberal Hegemony", always created laws in their establishment's favour, and even though its all skewed and manipulated, in their favour, they still break it all the time! It only really matters, if adversaries break it, if the American establishemnt does, its a minor issue probably being discussed, but it never has the same consequences. Otherwise the USA would have to bomb itself and imprison a large fraction of its current and former leaders...
A good take on the American hypocrisy, with detailled, concrete cases:

Just like Russia and Ukraine, the USA too have no moral higher ground at all. They just using different, more money and media driven, means for control, as long as they can. If the establishment would be threatened, from in- or outside, as are the Russian political leaders, how would they react? Still more liberal, still more tolerant? I doubt it. The power system is just different, and allows more freedom to the individual, because of their different goals and long term manipulation strategy. Other powers, which can't compete on that level, have to protect their states from this money & media driven influence from the US.
That's just logical and it isn't even about democracy primarily, because there were and are democracies under threat from the USA, and there were and are much worse dictatorships and systems than Russia under US protection and with US support. Its a geopolitical gambling of the US establishment, and with the Selenski regime, they now have their pawn in Ukraine which is ready to sacrifice his people to wear Russia down. Otherwise he could have made peace 2 years ago.
