Let me put it another way. He made us all as we are. He made them as they were. (Any addition to that is either direct, or indirectly as through other agency. Agency logically does not imply lack of causation, since he caused the agency to exist and act. But it also does not imply blame on his part, since agents and sinners are both willed creatures. On top of that, it does not in any case imply blame on his part, because he does not operate according to our economy but his. He owns it all, and it is all his to do with as he will. Any blame we find ourselves compelled to place on him assumes otherwise.)
To repeat, he made them as they were, and us as we are. The predilection of curiosity, if that was their downfall, or desire to improve their understanding, or even, perhaps, a natural inclination toward self-determination, may have been their downfall, yet in the end, they chose to disobey. Simple as that. THEY did it.
Likewise, and more obviously, people naturally are fraught with sin --slaves to sin-- apart from Christ. They choose according to their at-the-moment desires. And we regenerated believers also choose according to our momentary desires. Do we then blame God for making us as we are? No! We think that is simply base reality!
Also, to accuse God of wrongdoing in any of this structure, is to neglect the fact that he looks upon the heart to judge the deeds. That too, does not imply actual autonomous self-determination on the part of creatures. We do what we are.
I hope it isn't necessary to demonstrate the absolute logic of cause-and-effect in the matter. Fact does not contradict Scripture.
