One of the key questions related to the study of European and German history of the 20th century in particular is: Under what conditions did some individuals manage to offer resistance to atrocities such as happened in the Holocaust? And why did large masses ignore or even support blatant inhumanities and injustice? Understanding the underlying psychological aspects remains acutely important even in our democratic societies today, in which compliance, conformity, and indifference sometimes still seems to be the easiest way out of stress and insecurity.
