Societies and politics are two different things. Related, but different. Moreso when using politics to mean the art of statecraft as performed by politicians vs. the underlying strata of politics that informs society (a la "everything is political", which is often degraded as a left wing exaggeration. I agree with it, but that's an aside).Laws and morals are created, by societies, they don't exist out of the ether.
Whether you believe laws and morals should be shaped by politics or not, they are.
What is the calculation in service of though? Because it reads like a justification. If it's not a justification, what is it? Simply an observation?Who says anything about absolving anyone. This is a calculation. I do believe it to be a morally superior calculation than "all violence is equally bad" but no one gets absolved of anything.
