German-Jewish philosopher Hannah Arendt attended the war crimes trial against Adolf Eichmann in the early 1960s and reported on it in the New Yorker newspaper. Later she wrote a book entitled, “Eichmann in Jerusalem.”

In this book, she coined the phrase “the banality of evil.” She seems to excuse Eichmann’s acts not as the evil they were but rather regular, common acts of military officers simply obeying orders. During the trial, Eichmann stated that he did not kill anyone.
