I just saw a bumper sticker with the Gandhi statement that an eye for an eye leaves the whole world blind. Which, of course, reminded me of the Seven Psychopaths' Gandhi riff, that goes like this:
HANS: An eye for an eye leaves the whole world blind.
BILLY: No, it doesn't. There'll be one guy left with one eye. How's the last blind guy gonna take out the eye of the last guy left?
This, of course, is a question I have struggled with for my whole life. I expect the same is true for you.
