Both Camus and the Scholls opposed the murder and anti-humanism of the Nazis.
Camus was a pacifist who initially wanted to compromise with the Nazis as a way to atone for the Versailles Treaty, which had humiliated the Germans. However, he soon turned against the Nazis and in 1943 became editor-in-chief of an underground Communist Resistance newspaper called Combat. (After the war, he broke with the Communists for reasons similar to why he opposed Nazism.)
Camus was repelled by the cruelties the Nazis imposed on the French during the Occupation. He came to believe that the Nazi fixation with creating a utopic perfect future Ayran society led it to tolerate atrocities in the present. In The Rebel, he condemns of "massacres justified by ... a taste for the superhuman.”
The Scholls became aware of the Nazi policy of mass murder of Poles and the extermination of the Jews occurring on the Eastern Front during World War II. They opposed these policies as deeply inhumane and wanted the German people, who they thought were unaware of what was going on, to be informed of the acts perpetrated by their government. The group published and distributed pamphlets to publicize this information, a treasonous offense in a totalitarian state. The Scholls opposed the idea that there be only one version of the news. In their second pamphlet they stated:
Since the conquest of Poland, 300,000 Jews have been murdered in this country in the most bestial way.
Both Camus and the Scholls opposed murder and atrocity, feeling that human life and dignity were more important than abstract ideological goals.
