I don't think the British fighting were abusing powers. The violence to fight nazism was needed to end nazi rule in Germany.
The question is not if violence is useful, but when?
If, and that's a big if, you don't remember a thing, then things could have happened that you won't remember.
I don't actually believe that this is what happened, but it's not the rational slam dunk one might think it is.
I wish it is that way though. I don't want to relive the experience I went through earlier in my life.
My conscience ends.
If the materialists are right, the atoms I'm made of end up reforming my conscience into another mortal coil as a matter of statistics.
If they're wrong and there's a spirit that's not bound to the material world, I end up living inside another hull that accepts consciousness. Repeatedly. Could be human, alien, or that of an animal.
If that happens, I want to live in a world that respects all consciousness.
Must be nice living in that bubble of yours: https://www.reuters.com/world/europe/putin-growing-concerned-by-russias-economy-trump-mulls-more-sanctions-2025-01-23/
Or do you know the Russian economy better than its dictator?
What are those exceptions? That's the real question that needs answering.
