If you were to look at pictures of Nazi doctors without having any information about what they did during World War 2 you would think they were medical professionals who were dedicated to saving lives. In reality, they took lives and experimenting on Jewish prisoners. Experiments ranged from altitude, cold weather, poisons, intentional give prisoners gangrene and many more. German doctors completely disregarded their oath to never do harm. Mengele is probably the most recognized of the German doctors, nicknamed the Angel of Death. He would chose who would be gased immediately and who would work. He also performed experiments on the forced laborers. Most notably was his experiments on twins. All of these doctors should be regarded as villains.
