The Nazis were doing what many people in their society thought needed to be done.

It is a rather uncommon position (though, ironically, frequently a strawman position falsely attributed to their opponents to mock them by roughly the same political faction that backs the current ICE action) that “morality” is just whatever a sufficiently large number of people currently prefer.
