Yes, there will be no mercy because they have shown no mercy. Think of how many generations and hundreds, if not thousands of years these atrocities have been going on. Think of how many innocents have been brutally sacrificed to whatever deity from whatever ancient culture. It doesn't matter whether it was Phoenicia, Carthage, Babylon, the Mayans or Aztecs in MesoAmerica, Vatican City, or modern day United States/UK. It's all the same, evil people serving an evil force/spirit/entity, and now they flaunt it in our faces by trying to normalize their deviant behavior.
