There are some figures in modern history who stand out not just for their amoral conduct but their cruelty. This book explores the life of the notorious Beria, Stalin's henchman. The first part provides an outline of the turbulent history of Russia from 1900 to 1953, in order to set the background from which Beria emerged. The second section presents a biography of Beria from his youth, his early education, and his obsequious behaviour towards Stalin to his rise to be the head of the NKVD (KGB) and later to be amongst the most senior leaders of the Communist structure in the USSR. He was responsible for the deaths of millions (and for organising the Katyn massacre), infamous for murdering colleagues, and a sexual predator, and became the most feared man in the USSR next to Stalin. The third and fourth parts move away from history and biography to moral philosophy, in order to understand from where such evil conduct arises. The question of free-will is explored in the light of human insight, and these sections also discuss the most recent scientific claims concerning human behaviour, as well as the factors which influence people in decision making.
