John, Thanks for sharing your thoughts. The man on the steps is actually someone I got to know over a 4-year period, until he disappeared. He fell through the cracks of a system that failed to see the value in helping him, like many of the other homeless people I've photographed and/or gotten to know in NYC. The 'Do No Harm' principle isn't about telling anyone what to do; it's doing things that take the broad view of impacts our actions have, and understanding that we always have choices, and some choices add more value to more people, to the betterment of the whole. That's because the health of a society is no more than the sum of countless discrete acts. So, the more good choices we make, the better the outcomes. Food and health is a good corollary.
