How subjective. How do we know such a being would consider good something equivalent to what we consider it?
For example, what if good is defined by the lack of evil, and therefore all living beings should be eliminated, to remove the risk of sin? And then all matter would have to be...
An omnipotent, omniscient being would have no reason to do anything, including think about doing something or nothing.
I wouldn't wish such a fate on my worst enemy.
How about arguing who is being the most rational/logical? Surely only good can come by claiming someone is being irrational, illogical, and just plain silly.
