We kill at every step, not only in wars, riots, and executions. We kill when we close our eyes to poverty, suffering, and shame. In the same way all disrespect for life, all hardheartedness, all indifference, and all contempt is nothing else than killing. With just a little witty skepticism we can kill a good deal of the future in a young person. Life is waiting everywhere, the future is flowering everywhere, but we only see a small part of it and step on much of it with our feet.
