In Bless Me Ultima. What was the significance of Antonio's Dream in Chapter 14

This is Antonio's eighth dream in which Antonio attempts to garner salvation for his family. The voice of Heaven points out that Antonio asks for forgiveness for some and for punishment for others, something that is impossible. In the next part of the dream, Antonio witnesses the apocalypse prophesied by the golden carp; he and his family members are murdered by an evil mob, and everyone from the town is destroyed. Yet, Antonio’s vision ends with hope as the golden carp establishes a new world to make up for the old. In this view, the golden carp allows for both punishment and forgiveness and destroys the entire world only so that it can be remade in purity.
