“I will bring food and clothing to them, and then they will have morality. I will bring comfort to them, and then they will have faith. I am a traveler from a distant world, and I will bring the fire of civilization to In this dark and wild place, I know I am doing the right thing, eradicating famine, driving out disease, suppressing crime, ending war, and giving anyone who wants a change a second chance.”
