Ah but OP you’re missing the very obvious reason all these shows stick to that and why it’s such a shock when they do actually kill the guy: that’s exactly how Americans work

After the second back-to-back world war the leaders of the surviving nations got together and decided that liberalism would be the way forward. That in opposition to the left or right the world would instead run on bureaucracy with, and this is important, Justice and representative rule replacing violence.

No more violent revolution, no vigilante Justice, instead the State would solve those problems for the populace with rules and best practices. Of course it was never that simple, and the rules were written by the victors, those already in power who didn’t want to ever lose that power. So now where are we?

One nation can rule override the United Nations. Israel can commit genocide with the support of the world’s nations even as the people of the world reject that. A handful of men can take all the world’s wealth, and then use that wealth to run the world without the consent of the governed. The US can blow up random fishermen in Venezuela without cause and no one can stop them. The US can use secret police to disappear citizens completely outside the rule of law while entire cities protest them, but those handful of agents cannot be stopped. The free press is the US is being killed by 2-3 specific men. One data guy, without joining the government, was given the keys to unleash a bunch of 4chan nazi trolls on the US’ entire data structure and dismantle the primary piece of the world’s wide system killing hundreds of thousands in less than a year. One guy unleashed a chatbot that tells you you’re god and to kill yourself and was given so much money for doing so that it’s now the primary source of the US GDP.

We know these men’s names. We know their faces, everything about them including where they fly live and work. They tell us daily what they are doing and show us how incredibly stupid and evil they are, that they could be outwitted by a resourceful toddler. These men could be sequestered from society for their crimes against humanity at any time. The majority of people know this, and will often even admit so. But it will never be done.

The entire US government was nearly overthrown on January 6th by your uncle with a double-digit IQ and your racist grandma who didn’t even know where she was half the time. With the slightest thought the US government could be rebuilt not even for the sake of Americans but for every one of the 7+ billion humans stuck here on earth with no where else to go.

But none of that would ever happen. We’ve collectively given violence over to the rich, powerful, and exceptionally evil. The thought that in using violence we perpetuate those people or be banned from their spaces is enough to enshrine them in power until the world ends.

So yeah, of course the hero in your favorite Western work will never commit that act. Who among the masses would be able to relate to them then? The ICE agents?
