I'm not entirely an atheist.
But my greatest fear is that maybe there is a god. Because if there is a god, then the universe is a vastly more terrible place than if there is not a god. If there is no god, then all the horror and misery just happens. But if there is a god, then all the horror and misery is part of the plan.
That is fair. If humans ever get to the point where they cannot trust humans to do things, I would accept your point. While God's plan may include letting humans do their own thing without any intervention, I cannot accept that the plan is to intentionally hurt humans. If every human was hard wired to intentionally hurt other humans, we would be in a lot more trouble than we are. There are a lot of humans who show self restraint. That God has the ability to do so seems to indicate that his plan has restraint also. So while there is a lot of hurt and suffering, that does not mean it is part of the plan, but just allowed to go on due to the current nature of human existence.
I don't see how things could be perfect and humans still do whatever they want to do. But then again perhaps humans would not want to do anything harmful to others. That already happens though. Even if we could hurt another human, and 2 seconds later that human would get up and go on like nothing ever happened, would the world sustain human immortality? Would there be enough humans to figure out how to get off this planet and go to other star systems, if they could organize their thoughts just on that goal? What would humans do if they could not hold control over other humans? Would humans even form groups, or would each person just do their own thing, and nothing would ever get done?
Well yes and no.
There are things which we don't know anything at all about. Absolutely zero. We don't even know we know nothing about them.
And other things that we know something about, e.g. God we've heard referred to and some people maintain that it refers to something real.
And some other things that we know something about e.g. leprechauns - I mean I even know how to spell leprechaun - and only the criminally insane apparently think these are real.
I'm not really sure which of your axioms you're using to determine which category you slot these three into.
I think any one can put God into the no reason box, if they themselves deny another human's reason not to. I don't think any one can control what other people can reason unless they control the input of knowledge. Once knowledge is there, you can choose to reason about it or not. You can deny it or not, but once again, one can only do that for one's own self and not any other human, unless we get back to keeping other humans from obtaining any knowledge. Blocking knowledge though goes against the scientific method, unless of course such knowledge can be reasoned away, or outright denied.
Today humans have convinced themselves that the Bible has been proven wrong in enough instances that one can even rule out God. I do not adhere to God of the gaps, because God can be represented via humans on earth, even though other humans can become increasingly self sufficient without God. Perhaps the Bible has gaps itself to allow humans to fill them in as they gain knowledge. I don't think they will ever prove the entirety of the Bible away though.
