What does Tony feel after witnessing the death of a man for the first time Bless Me, Ultima?

When Antonio witnesses the death of Lupito on the bridge, he is horrified and runs home, where he is comforted and cared for by Ultima. That night, Antonio dreams of his brothers and of Lupito's soul.
The death of Lupito causes Antonio to begin thinking about mortality and of the souls of humans after they die. He struggles with wondering what has become of Lupito's soul. He ponders if Lupito is sent to hell for murdering the town sheriff, if his soul has been forgiven by God, or if he is destined to remain as a ghost, haunting his place of death by the river.
Antonio is disturbed by how quickly the men on the bridge shoot Lupito and how so few men argued against killing him. He wonders how men who claim to be respectful of life can so quickly be moved to murder.
