Re: “All knowing”
That is the essence of my position.
God does not influence it. He lets the person decide.
Hence the person is responsible of his/her act.
Same way, if I gave the child two items. The child decides on his/her own. Not me.
Regardless of what God knows anyone in this world would do, and I knew what the child would do, it makes the person and the child in my example act on free will. Like I said, don’t blame God for wrong choices you (not personally you) make.
**God will judge you for the action you had control on, not when you did not.
**
With all of his mercy, God/Allah gives a lot of chances to human and waits before He decides to put the person responsible.
There is a limit however where human have ability to choose. **And when the ability to choose is not present then, human are not to be punished for their acts.
**
If I get time, no promise but I will write more and basic rules of engagement between God and Human and that will answer 5amra also. Stay tuned. 
P.S. Good questions by the way.
