Tens of thousands of Catholic priests were murdered in concentration camps.
Hitler raised taxes on the rich and confiscated their wealth. He was all for class warfare
The higher levels of the army was purged of all non party (Nazi) members
"Tens of thousands of Catholic priests were murdered in concentration camps."
As was Dietrich Bonhoeffer, the outspoken anti-Nazi Lutheran pastor. From a bio: "Dietrich Bonhoeffer was born in Breslau in 1906. The son of a famous German psychiatrist, he studied in Berlin and New York City. He left the safety of America to return to Germany and continue his public repudiation of the Nazis, which led to his arrest in 1943. Linked to the group of conspirators whose attempted assassination of Hitler failed, he was hanged in April 1945. He was executed by special order of Himmler at the concentration camp at Flossenburg on April 9th, 1945, just a few days before it was liberated by the Allies."
The evil must always destroy the good, no matter whether it furthers their goals or not. It's a compulsion to them, simply because the existence of goodness reproaches their evil.
If you haven't read Bonhoeffer's "The Cost of Discipleship", you might want to. It's a powerful classic, and he certainly had the moral stature, had demonstrated the moral fortitude to be a credible writer on the subject.
Not all the Army was purged of non-Nazis. von Rundtstedt was kept, retired, and called back toward the end. He is one example. Hitler needed him. Toward the end of the war, there were even Muslems in the German army.
Germans were not Catholics...they were Lutherans....
