Mengele ultimately decided the Jew’s fates when they arrived at Auschwitz. Twins interested Mengele highly and most operations were performed on twins. Before the twins were operated on, they were given sweets and even were allowed to wear their own clothes. Mengele let them call him “Uncle Mengele” in attempt to keep the twins as calm as possible. (“Mengele’s Children- The Twins of Auschwitz”) Mengele tortured twins for his own personal enjoyment and gain. There was absolutely no scientific evidence to support his procedures. Every time he killed, he did so with no sympathy or mercy. Stories of Mengele’s tortures were often upsetting and brutal such as the time he gassed a while block of women because the had gotten lice. Mengele didn’t limit himself to twins and other “misfits”, he killed anyone he wanted to just because he could. He liked the suffering of other humans. Mengele hurled an infant from a mother’s womb into his oven because it was not a twin like he had hoped.
