For although you have not actually committed all these crimes, as far as you are concerned, you have nevertheless permitted your neighbors to languish and perish in their misfortune. It is just as if I saw someone who was struggling in deep water…and I could stretch out my hand to pull him out and save him, and yet I did not do so. How would I appear before all the world except as a murderer…?
