 Some Holocaust survivors have criticized the portrayal of Dr. Weiss  after he becomes a prisoner of Auschwitz, because his character is  portrayed as working on road gangs and paving crews. Jewish doctors  in Auschwitz were almost always assigned to the camp infirmary and  placed in the moral dilemma of serving under German doctors. These  Jewish doctors endured an "agony of conscience" as they were ordered  to help prevent the spread of disease from Jewish inmates to German  captors, and also participate in medical experiments and, in some  cases, even selections for the gas chambers.
