It can be seen from history that God has permitted many acts of barbarism against good and evil people, be it Aztecs who ripped out the hearts of people who just wanted to work their crops, to children of all lands that were wiped out with their mothers and fathers, to people living in Israel when the Jewish people were coming in, to Christians wiping out the Cathar and Waldensian Christians and Muslims ransacking and pillaging towns in the Byzantine ear up until today.
Oops, I meant to say “Byzantine era...”
