Great academic study about the process of vilification of groups. The author chows great passion and impartiality in the topic, by presenting cases of far-right people terrorizing minorities and authorities terrorizing far-right people. The book analyzes how no one admires to be evil, but instead construct a narrative where they are the victim of a hateful group, and there for they must trike first. So "evil" is more a question of perception than a actual ontological state. Still evil exist and no one is free from doing evil. So this is a great sociological study of violent radicalization, hate groups and the warped belief in "pure heart" heroes.
