If we’re aggregating cooperation rather than aggregating values, we certainly can create a system that distinguishes between societies that apply an extreme level of noncooperation (i.e. killing) to larger groups of people than other societies, and that uses our own definition of noncooperation rather than what the Nazi values judge as noncooperation.
That’s not to say you couldn’t still find tricky example societies where the system evaluation isn’t doing what we want, I just mean to encourage further improvement to cover moral behaviour towards and from hated minorities, and in actual Nazi Germany.
