Halcon: We've established that God is both capable of giving eternal punishment and eternal reward
We both have accepted this as a given.
So, we have a god who designed a universe where people will always suffer. He himself understood this, as he noted that a lot of people would choose the path to destruction. He gave humanity a choice between bliss and suffering, knowing that many would choose suffering. He could have eliminated that choice and offered only bliss. Then, no one would suffer, which is something he claims to want.
So, even if we blame humans for their choices, we still exist in a universe where god knew that most would suffer. And they would suffer for all eternity. There will always be suffering in his universe, regardless of who we blame. Even if we take the step of absolving him for the failure of a population that he designed and created, we have a universe where there will always be suffering. It seems to me that he wants there to be suffering.
We do have the thorny issue of god allowing a condition to exist that is in direct opposition to what he claims to want. Thus, we must assume he is confused or lying. Neither of these is a bad thing, since we cannot judge him on human terms. They simply are. This also is not altered if we accept that his god is omnipotent, omnipresent, and omniscient. He can be all of these things and still be beyond our notions of good and evil, so that his duplicity and desire for the suffering of others are true for him, yet not a good or bad thing.
