How can a god be good?
God is a word pointing to itself.
Banana is a word, representing a fruit.
The word God, represents the word.
Even if the concept shares a perfectly identical truth out there,
The word still points to the fabricated concept, because the person uttering the word is not intending the facts but the fiction.
The word fiction points to itself also.
So if I produce a movie and want to present it as fiction,
This is a story of God,
Is just as expressive like advertising,
This is a story of fiction.
Fiction points to an assumption, no less than God does.
So maybe asking why the assumption is so wicked and cruel,
I would ask why is the assumption?
