Dr. Josef Mengele was known as the Angel Of Death because he was always immaculately prepared for the long-drawn-out rituals of death. He was one of the most infamous men associated with the death camps and the Holocaust because of his experiments on twins. Although Dr. Josef Mengele was thought of as evil and inhumane due to his unethical experiments on humans, he fundamentally influenced our modern understanding of human physiology, he was a human being that loved, lived, and had a family, and he justified his ethics as he was just trying to help the world evolve.
