The S&M sex scene knows more about suffering and unbearable suffering than the institution of psychiatry knows. There is a safe word to prevent suffering from becoming unbearable suffering. The safe word idea is the definition of mercy bur no psychiatrist can understand why mercy is important. They think unbearable suffering is a product of a brain defect so no mercy is necessary. The medicalised suicide system has prisons instead of sanctuaries and there is no mercy there.
