5. Adolf Eichmann
For a while, it seemed that Adolf Eichmann, one of the most evil Nazis ever, will manage to evade justice for his atrocities committed during the war as one of the main organizers of the Holocaust. The notorious Nazi SS-Obersturmbannführer escaped from the prison in 1945. After spending some time hiding in Germany, he relocated to Argentina in 1950. Mossad caught up with him in 1960 and grabbed him from Buenos Aires. He was tried and sentenced to death in Israel.
