Actually, the Pope never endorsed Hitler in the 30s. On the contrary, he wrote and circulated an Encyclical in Germany, called « Mit brennender Sorge », which was clandestinely imported and read at Sunday mass in every German church, and roundly condemned Nazism as pagan and antinomic to Christianism (triggering a wave of repression against priests). It’s worth noting that it’s one of only two Encyclicals that were not written in Latin.
