He is a person with a debt of grievance on his body, in his own world.
He met the boy, and the boy took him into his own perspective. When he realized that his "reformer" turned out to be a dying patient, his eyes blinded by hatred slowly saw the truth of the world clearly...
He stepped out of his own world and returned to the real world.
He is a human being, not a god. There is no god in the world. If there are too many people praying, a god will become a virtual god.
Friendly reminder: independent perspective.
Purpose: Save yourself before saving others
