"This book looks at the politics of our times and the roots of human nature to discover why so many atrocities were perpetuated and how we can create a social environment to prevent their recurrence." "Jonathan Glover finds similarities in the psychology of those who perpetuate, collaborate in, and are complicit with atrocities, uncovering some disturbing common elements - tribal hatred, blind adherence to ideology, diminished personal responsibility."--BOOK JACKET.
