Thats actually a tool of genocide. The whole point of creating the gas chambers was to create an efficient genocide machine. The guards who took the prisoners to the chambers were different from guards who took the bodies. The guards who interacted with the prisoners weren’t allowed to decide who got to live and who did not.
All in all, the chambers gave the guards a sense of “we are just following orders” feeling thus lessening their guilt. Because no matter how cruel it is, the humans will feel guilt.
The calling for evacuation is also a similar tool to lessen the guilt of the soldiers. Afterall, those people who died were told to evacuate therefore their death is on their hands.
This is a by-product of modern society (maybe late stage capitalism). We need to be sold a “solution” to a problem. Reducing consumption is not something that can easily be sold hence these carbon capture, recycling plastic “solutions”.
Unless someone can make money off of it, reducing emissions is going to be difficult.
