But you aren't God, so you have no actual control over what your son does. Any control you have is a result of complex emotional responses and the illusion of you being in charge of your son. In theory, he can do whatever he likes unless you physically stop him with your superior strength and size. If your son was about to run into the fire or jump off a cliff and die, would you physically stop him? If so, then your analysis of the similarities between your mother-son relationship and God's relationship with Adam and Eve is invalid because you would show a method of force that God didn't show to Adam and Eve.
If God knew what will happen, and allowed it to happen, and created man with the ability for it to happen, and instated the laws that dictated everything that would happen and the consequences of every action, then God created us into a situation that could never have happened any differently, because he knew it EXACTLY how it would happen before it did yet didn't do anything to change it.
Imagine oyu knew your son in entirety, and had complete control of all his surroundings and how he was actually made, down to every detail. Then imagine him sentencing himself to death through sins, and you allowing it and actually creating the parameters for it with all the knowledge and power you have.
