Um...since when? Are you trying to mansplain life to GOD? Are you trying to tell God how it is? Where is the fear of God before your eyes, that you drag Him into the argument to say that if you are wrong, God was duplicitous and disingenuous? I mean, your argument is wrong, so all God sees is you saying that He was duplicitous and disingenuous with Adam. Do you consider the consequences of your arguments. I mean, one day you will have to make account for yourself, whether through the fires of testing (sanctification), or final judgement. A pile of ash, a pile of gold and polished gems, or an eternity of separation from God.
God has a sovereign plan. Even the doctrines of Grace speak of it. We are saved by grace alone, through faith alone, in Christ alone, and (God's sovereign plan) to the glory of God alone. God told the Israelites more than once what His plans were. Why did He destroy Egypt, instead of simply bringing Israel out? He could have stopped hardening Pharaoh's heart, and no one in Egypt would have to suffer having their first born children killed by their Creator. And what about the consecration of the first born. How are they consecrated to God? They are slaughtered. However, God made a way to redeem children of humanity by sacrifices. Even Jesus was redeemed by the sacrifice of two pigeon doves. The first born of all the cattle and livestock was to be sacrificed. (Take that vegans...(sorry, have had too many vegan posts show up in my social media feeds)).
If God foreordained Adam to sin, and made that determination, there is no programming involved. It is an end state. It simply says "Adam will sin". There is no force within that statement that makes Adam sin. It is an end state. Even you said "by default ADAM ONLY DID..." Adam did it. The rest of that sentence is meaningless in the face of logic. Adam did it, and therefore Adam bears responsibility, as does the rest of his offspring. This is not the sovereign plan of God, but one of the many moving parts that brings us to the revealing of His sovereign plan, which you can find at the end of Revelation. So, I ask again the question I asked earlier. Where is the fear of God before you eyes?
