Here's a teaching moment. This debate is about to go on a deeper level than you've taken it so far. We are going to distinguish metaphysical obedience from moral obedience, then I'm going to prove you wrong.
God is sometimes morally disobeyed yet He is always metaphysically obeyed. In other words, there is a difference between ontology and moral law. You seem to confuse the two. When you think 'ontology', think 'metaphysics' - it basically just refers to the most basic sense of things. Though Scripture teaches Determinism, you shouldn't even need to accept Determinism in order to understand the differences between these two concepts.
Daniel 4:35
And all the inhabitants of the earth are reputed as nothing: and he doeth according to his will in the army of heaven, and among the inhabitants of the earth: and none can stay his hand, or say unto him, What doest thou?
This verse speaks of ontology. None can stay His hand. In other words, no one can disobey God's power. Therefore, when God causes a man to do something, it means the man metaphysically obeyed God, and it means you would be wrong if you claimed obedience requires a choice.
As a Christian, I assume you know that His moral law can be disobeyed, so I shouldn't need to establish that. We both agree sin exists.
Now all I need to do is show you atleast one case where God metaphysically caused men to morally disobey Him, and I will have proven you wrong, because this would mean that God can be disobeyed while controlling everything.
Scripture teaches that the Lord morally demanded men to not partake in acts such as the Crucifixion, yet the Crucifixion was metaphysically of His doing and will.
Exodus 20:13
Thou shalt not kill.
Isaiah 46:10
Declaring the end from the beginning, and from ancient times the things that are not yet done, saying, My counsel shall stand, and I will do all my pleasure:
Isaiah 53:10
Yet it pleased the Lord to bruise him; he hath put him to grief: when thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the Lord shall prosper in his hand.
Acts 4:27-28
For of a truth against thy holy child Jesus, whom thou hast anointed, both Herod, and Pontius Pilate, with the Gentiles, and the people of Israel, were gathered together, for to do whatsoever thy hand and thy counsel determined before to be done.
There it is. If you are familiar enough with Scripture, you will see with these verses that God has determined by His will and caused by His power the Crucifixion - man's greatest act of evil in history.
