Vilifying Pinochet—Cui bono?
There are two groups who can benefit from the vilification of Pinochet.
First, there are wannabe dictators-for-life. Vilifying Pinochet will deter anybody who might want to suppress a revolution and then step down. The opposition will be limited to other would-be dictators-for-life—a much smaller group. Any dictator who steps down voluntarily should be given the benefit of the doubt.
Second, there are the neo-Nazis. They have claimed that Hitler is vilified because he was anti-Communist. The obvious retort—until now—was that other anti-Communist dictators have not been similarly vilified. Vilifying Pinochet will give neo-Nazis some superficial plausibility.
