It's the classic battle of the little devil on one shoulder vs. the little angel on the other shoulder. The "little halo" is the angel. The man on whose shoulders rest the devil and angel has been listening to the devil, and as the angel fights to gain control, the man tells the angel he isn't interested. The man feels he's been evil, or bad, enough... why stop while you're ahead and in control?
