Those that conclude God could be doing a better job don't really understand the implications of their demands as I have partly brought out. They see injustice and cannot comprehend how an all powerful God could let this happen.
Or perhaps they do understand and can comprehend how, and that is part of what leads them to conclude that the God is not worthy of worship.
This idea of yours that if people just understood and comprehended like you do then they would agree with you is not in the slightest bit convincing.
They don't understand he cannot exercise great power like that without inevitable consequences, so he is not all powerful, it is limited by the huge interconnectedness of life.
They could also consider this God of yours that is impotent as not being worthy of worship for that reason.
In my mind, God is doing an excellent job at justice given his constraints I have tried to illustrate.
You mean: constraints that you have invented.
Even granting your constraints, it still isn't necessitated that the God is worth of worship.
If there is an afterlife, I suspect all remaining injustices will be corrected and it will not be a pretty sight. A metaphor called the lake of fire tries to give a sense of it to our imagination.
Well that God is a jerk, so He's not worthy of worship.
