The lost brother as a "god" is a blasphemous figure. But the lost brother as a metaphor is worth ruminating on.
God creates a perfect world, but their brother disagrees with how it is made. The brother leaves, angry at not being listened to. God grows lonely over time in their perfect world, and seeks out their brother, saying that they will listen to them, wanting them back.
The brother seems pleased at first, but the advice they give is horrible, and the world quickly takes a dark turn.
When God attempts to undo the damage, the brother strikes out in anger, killing God.
The world fully collapses into chaos, and the brother flees (or dies perhaps).
In the end a perfect world is destroyed, and nobody is happier for it.
The lesson I take from this story is that true perfection must come from a single source, a single mind. Do not attempt to compromise that vision to appeal to others, lest it ruin everything.
Not even family should come between you and what must be done.
