How does the story of the White Rose prove that Germans were not homogeneous during WW2?

The answer is below

Explanation:

White Rose, is a German anti-Nazi group, formed by some medical students named; Hans Scholl, Willi Graf, Sophie and Alexander Schmorell, all from the University in Munich in 1942. The purpose of White Rose group is to seek and support nonviolent resistance as a means of opposing the Nazi regime, who are annihilating the German Jews.

These founding members were eventually seen as opposition to the Nazi regime, and were later arrested and executed, while also jailing other citizens found to be in support of White Rose group.

Hence, this clearly showed that, Germany, were not homogeneous during the World War II.
