4. Reinhard Heydrich
Up next on our list of most evil Nazis ever is Reinhard Heydrich that was the brain behind the Holocaust. He was often described as the darkest figure in the Third Reich, and that is saying a lot, considering the competition he was facing for that title. Even after his assassination by the Czech resistance in 1942, he managed to strike at the Czech people. Lidice massacre, ordered by Hitler himself as a retaliation, saw some 1,300 people killed and the towns razed to the ground.
