Good point, still I would not have added him in the poll. Ok, my poll is not completely correct - it is not about the most disgusting 3rd Reich person, but the most disgusting important and/or very well-known 3rd Reich person.
Dirlewanger is a good example to prove my point of the SCALE and NATURE of crimes... Dirlewanger killed, raped, stole and tortured a lot of people with his OWN hands! He was nothing more than an animal, a vulgar beast with any human feeling in himself... Heydrich never behaved in such beastial way. But he killed 1.000.000 times more people than Dirlewanger with his signature. Therefore, Heydrich is the worst criminal in SCALE and Dirlewanger is one of the worst in NATURE. They are not AS disgusting AS the other.
My Vote went to Mengele, but I believe we missed 2 very despicable characters from the Third Reich:- Ilse Koch and Oskar Dirlewanger
To justify it: If you look around in google for those nazis, you get about: "Adolf Hitler" 419,000 "Joseph/Josef Goebbels" 32,800 "Hermann Göring" 31,400 "Heinrich Himmler" 25,200 "Adolf Eichmann" 22,400 "Josef/Joseph Mengele" 14,600 "Reinhard Heydrich" 10,600 "Martin Bormann" 6,900 "Roland Freisler" 1,500 "Ilse Koch" ~600 (this is a usual name, so it's difficult to filter her out) "Oskar/Oscar Dirlewanger" 150 Hmmm, indeed I underestimated the publicity of Koch. Doesn't matter, at least she is definitely the most disgusting woman in history.
It's very difficult to make a chose between e.g. Eicmann, Heydrich of Mengele. I really don't know who was the most horrible of those three. Was it Eichmann who planned the mass murder on the Jews and other ethnic groups or Heydrich who gave the commands to bring Chezks, Jews, ... to the concentration camp. Or was it Mengele who worked as a "horrible" doctor in Auschwitz, who did experiments on people, ... .
There is also a lesser known character...he is so unknown that I have never heard him named. There is a photograph of Einsatzkommando killing Jews in the early days of the Russian campaign. He has just shot a person, and he is laughing!!!! Is that sick or what!!!
Some others who deserved a first class ticket to Hell: -Rosenberg who promoted slave labor in the most terrible way in Russia or Ernst Sauckel who organised slave labor in genral. Let's not forget HANS FRANK the infamous governor of Poland, Karl Babor, Mengele's the Fenol expert at Gross Rosen. Babor was considered as a small fish and got away, but I personnaly think he was one of the sickest.
