Hominid bipeds are divided into two categories: “people” and “targets”.
I'm thinking of Amon Göth, commandant of the Kraków-Płaszów concentration camp in German-occupied Poland. He was memorably portrayed by Ralph Fiennes in the movie Schindler's List.
Herr Göth certainly believed in your two categories.
One of the Schindler survivors (Poldek Pfefferberg) described him with these words: "When you saw Göth, you saw death."
