The book examines the Nazi T4 euthanasia program, cases of biological weapon use, notorious experiments on twins, and a wide range of other trials: sterilization, exposure to mustard gas, transplantation of bones, muscles, and nerves, studies of traumatic brain injuries, stabbing and cutting wounds, freezing, tests under sharp pressure changes, infection with malaria, use of sulfonamides, research on viral hepatitis, electric shock, phosphorus burns, and trials of poisons and toxins. This is not just a historical study, but a grim reminder of what human beings can do when ideology displaces morality.
