If I created the house with my bare hands as well as the rest of the world and then proceded to create these individuals intentionally so that they would make mistakes it still seems like a dick move for me to blame them for doing what I designed them to do in the first place.
What Adam did was not a mistake. It was a willful act of rebellion. Neither did God create them to do bad. They were perfect humans with no inborn tendencies to sin. I believe it is as Deuteronomy 32:3-5 explains:"For I will declare the name of Jehovah. Tell about the greatness of our God! **The Rock, perfect is his activity, For all his ways are justice. A God of faithfulness who is never unjust; Righteous and upright is he. *They are the ones who have acted corruptly. They are not his children, the defect is their own." The fact that Jesus Christ led a faultless life of integrity to God as a perfect man shows that Adam and Eve could have done so. (1 Peter 2:21,22)
