Studying the motivations of those who actively participated in the Holocaust and trying to understand them is no easy task. There have been many attempts to do so ranging from a simplistic 'they must have been monsters' view to 'they were victims of their circumstances'. But neither captures the true complexity of interacting causes of any one person's behaviour nor the slippery-slope aspect of increasing brutalisation through participation. Sadly for humanity's peace of mind, there is probably no simple explanation for why anyone actively participates in genocide - if there were we should have been able to prevent its regular reccurence since 1945. However, David Cesarani goes a long way to reaching the most balanced view I've yet read to date.
The book assumes that you are reasonably familiar with the facts and chronology so a novice of the era would probably struggle to keep up with the narrative. Cesarani takes you through Eichmann's life until his kidnapping by Israeli agents in Argentina at a fair pace, occasionally skimming events that you might have wanted covered in greater detail. But this is not a book about what happened - it's looking at Eichmann the man, and so the author rightly (in my view) does not dwell on the untold misery and horror that he inflicted from afar (and witnessed on occasion at close quarters) on millions of innocent people. He then goes through his trial in Israel in great detail giving as much attention to the trial as to Eichmann himself. It becomes clear that the trial needed to serve the interests of the State just as much as the interests of Justice, but nevertheless, the verdict is no surprise to anyone except perhaps Eichmann himself. And here lies the clue to the real man within. Eichmann lived a life so full of self-delusion for so long that he found it impossible to separate the spark of real humanity left within his corrupted soul from all the conceited self-justifications, lies, propaganda and, ultimately, anti-semitism that had so taken over his life and his sense of Self.
The book ends by assessing Eichmann's impact on history and the debate over the Nazi Final Solution. He takes time to argue against Hannah Arendt's views as expounded in her book of the trial (The Banality of Evil), claiming she was only interested in pushing her personal theory, and because of the huge publicity she achieved, how she warped the ongoing debate. This book certainly addresses this and puts Eichmann back into a more balanced, and in my view, more realistic place.
Cesarani leaves you with a view that although Eichmann was made by his circumstances (he could never have become a genocidaire without Hitler's Nazi state), he was ultimately personally responsible for allowing himself to be sucked into the machinery of genocide. In other words, Eichmann started out as normal a person as you or I, but he chose the path he trod - and, quite rightly, his end was that reserved for a monster.
