Using this[1] map created from the Dutch census data (which included religious affiliation), the Nazis were able to very efficiently send about 3/4 of the black dots on that map to be murdered in the camps. Collecting that census data probably seemed reasonable at the time. The new use case that needed a new way of aggre4gating and presenting the data happened later, almost as an emergent property. The only y to prevent problems that haven't been invented yet is to minimize the attack surface: if the records don't exist, they can't be misused.
