"For my thoughts are not your thoughts, neither are your ways my ways," declares the LORD.
As the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts."
– Isaiah 55:8-9

Even if God were any of the things you don't like, He would still be God -- and therefore free to make his own rules.

For I know the plans I have for you,” declares the Lord, “plans to prosper you and not to harm you, plans to give you hope and a future.” – Jeremiah 29:11

Pretty pointless to spin up straw man arguments about what God does and does not know and what he does and does not choose to control. We rebellious humans tend to act like children who can't understand why their mean parents won't let them eat a whole box of chocolates.

So why not start with the answers He has already given us:

In the beginning God created a perfect world with minimum rules and gave us free-will dominion over it. We rebelled (as He knew we would) and sent ourselves on a 7000 year detour during which history has allowed us to try and fail at every possible way of governing ourselves. During that time, in every generation, a very small remnant of humanity reached the desired end-state of freely choosing to do things God's Way. To those God gave the right to be adopted as "Children of God" and those are the ones He intends to keep at his final "harvest". The rest of the weeds are to be discarded as not useful. Do you have a moral problem with composting weeds?

He could have created obedient robots, but He wanted a family He could trust. Children that would choose Him of their own free will.

There. No need to speculate. God wanted to create free will beings to become members of his family. This current temporary universe is there only for that purpose. Its a simulated training ground and a test range where candidates are given the chance to figure things out, straighten up and fly right... or not.

Then God will press "reset" on the simulation and turn the renewed creation over to qualified family members who have proven under high pressure life-or-death conditions with woefully incomplete information, that they will choose Him rather than making up elaborate excuses about why they don't have to.

Pretty simple really.

We now return to our regularly scheduled program where the weeds talk about how much they don't want the Gardner to exist.
