Through the bibliographical study of Aldolf Hitler's life, the parallel reading with the clinical analysis of behaviour, his marks, traumas and their possible effects, leading to his future acts, which resulted in the greatest massacre in history. It seeks to understand what triggered his obstinacy for the Jews and his need for power. In order to discuss the similarities of current events with the beliefs and ideologies preached by Hitler and Nazism in the past. It concludes that civilization has always been marked by a malaise and, as in Hitler's story, since its origin, there was a need to live the idealized, which returns in fantasy, and that the marks left by his parents, traumas and the environment were fundamental for the development of his personality. After 70 years, we can find Hitler's fashions around us, but they have other names, and the jurisdiction is trying to keep control over the facts, which often go unnoticed to our eyes, because our current society is exclusive and prejudiced. We want to erase the violence and discrimination not only from Hitler's day, but also from our day.
