The camp administration gave him the "black triangle" badge of the "asocials" because he was accused of homosexual conduct as well as anti-Nazi activity. He was one of the few priests imprisoned in the Dachau KZ to survive the work caring for inmates dying of highly infectious typhus at the end of the war. Roth remained in Dachau as a priest for the SS men interned there by the US Army after July 1945. When that internment camp was dissolved and the Bavarian government converted the camp to housing for German refugees from Czechoslovakia in 1948, Roth remained as their "curate" (he had been demoted from priest status). A stern but well-liked pastor, he worked tirelessly to better the living conditions of the refugees. Around 1957 he joined the Dachau camp survivors' organization as a representative of the priests who had been imprisoned in the camp. By 1960 he was in heated conflict with the Catholic hierarchy in Bavaria. Relieved of his post in the refugee settlement, he took his own life.
“At this point in the war and in his life, I think Oskar Schindler was absolutely determined to do everything he could to save as many Jews as he could regardless of the cost, either personal or financial,” writes Crowe. “During the last two years of the war, he had undergone a dramatic moral transformation, and, in many ways, he came more and more to associate himself with his Jews than with other Germans.”
Peter Hayes (How Was It Possible? A Holocaust Reader, 2015): "The Holocaust, the Nazi attempt to eradicate the Jews of Europe, has come to be regarded as the emblematic event of Twentieth Century ... Hitler's ideology depicted the Jews as uniquely dangerous to Germany and therefore uniquely destined to disappear completely from the Reich and all territories subordinate to it. The threat posted by supposedly corrupting but generally powerless Sinti and Roma was far less, and therefore addressed inconsistently in the Nazi realm. Gay men were defined as a problem only if they were German or having sex with Germans or having sex with Germans and considered 'curable' in most cases. ... Germany's murderous intent toward the handicapped inhabitants of European mental institutions ... was more comprehensive ... but here, too, implementation was uneven and life-saving exceptions permitted, especially in Western Europe. Not only were some Slavs—Slovaks, Croats, Bulgarians, some Ukrainians—allotted a favored place in Hitler's New Order, but the fate of most of the other Slavs the Nazis derided as sub-humans ... consisted of enslavement and gradual attrition, not the prompt massacre meted out to the Jews after 1941."
The camp was liberated on April 15, 1945, by the British 11th Armoured Division. The soldiers discovered approximately 60,000 prisoners inside, most of them half-starved and seriously ill, and another 13,000 corpses, including those of Anne and Margot Frank, lying around the camp unburied. The horrors of the camp, documented on film and in pictures, made the name "Belsen" emblematic of Nazi crimes in general for public opinion in many countries in the immediate post-1945 period. Today, there is a memorial with an exhibition hall at the site.
