Big words, like good and evil, come with lots of emotional baggage, little of which stands up to logical scrutiny. The rhetoric of evil drags terms from old-time religion and serves the political class by oversimplifying moral and political complexity, a kind of instant moral sound bite. Is money really evil? Or all of capitalism? Or the western world as if personifies only the worst of humanity? What applies to individual morality works much less well with abstract institutions.
