To help ground it in a more down to earth context, for an example of something non-political. For my part, I would have been happier if a certain co-worker had not been so indulged. She demoralized everybody. But the boss was her friend. She would run out any time she felt like it. Everything she did, she messed up, and the mess got passed to somebody else. So, in my little corner of the universe, if the boss had not let her friendship with this woman compromise her objectivity, it would have been kinder to the rest of us. As it was, her kindness to this woman was a cruelty to many other people.
In expressing the principle as I have, what I hope to happen is for people to recognize this principle and then to make better decisions as a result. I don't hope for any specific political program.
