The straight answer appears to be no. The camps were known, the scale of the inhumanity was wholly unbelievable.
When the Germans were advancing back to protect Berlin, they used death marches to escort them to German concentration camps, but some prisoners were left behind, and when allied troops advanced, the surviving prisoners told them their story.
The Nuremberg Trials put officers from the German High Command responsible for war crimes to justice. Among the war crimes that they were convicted of were atrocities committed in the concentration camps.
There may be a misunderstanding here. The Allied armies entered Germany in order to defeat the country militarily, not in order in liberate people from concentration camps: that was, so to speak, an added bonus.
There is no historical evidence or information available to suggest that Hannelore Schmatz had any role or job in a concentration camp. Hannelore Schmatz was a German mountaineer and not associated with the atrocities of the concentration camps.
Nuremberg
Nuremburg
German war criminals were tried for atrocities during World War II in the city of Nuremberg. The Nuremberg Trials took place from 1945 to 1946 and aimed to hold individuals accountable for their roles in war crimes, crimes against humanity, and other atrocities committed during the war.

The Soviet Army suspected most SS men of having committed atrocities. If they could, SS men tried to get taken prisoner with ordinary regular German soldiers and remove the tattoo.
Definitely not. To resist the Nazi government was death to a German citizen (or anyone else for that matter). They most certainly would've been killed had they staged protests.
