Well it makes more sense than killing thousands upon thousands of pagan Slavs, Jews, Russian and Greek Orthodox Christians, Mongols, Cathars, Hussites, Waldensians, Old Prussians, and political enemies of the popes in religiously-sanctioned military campaigns doesn't it? Oh, wait... that happened didn't it? Ah well, so long as it was all in the name of God that makes it alright I guess. Go Christians!
