Your question seems to be more along the lines of why God would make beings that make the wrong choice, or make beings that have limited knowledge, rather than how creatures could possibly make the wrong choice. Is this a fair reading?
I think this is true. God cannot make another God, no matter how great a being He makes. So the greater the freedom He gives to His creation, the greater the risk for evil to manifest itself because that freedom is given to a
necessarily less-than-perfect being, relative to His absolute perfection. At the end of the day His purpose is for creation-in the form of angels and humans- to come to know its place, and
His place-for its own good, in order for truth and justice and harmony to reign. And that necessarily involves everything being subjugated to Him in love and worship. In our own stubborn pride and ignorance we suspect that this might be a prideful thing
itself, His desiring this worship, not yet capable as we are of perceiving His incomparable goodness-and jealous of it perhaps, truth be known.
But Christ’s main purpose is to thwart that very notion, to overcome the “distorted image of God” that the Church teaches man conceived of at the Fall by revealing His true nature when the time was ripe in human history, to reveal a God who would even suffer an extremely humiliating and painful death on a cross at the hands of His own wayward creation to prove just how much He values humility, just how kind and merciful and forgiving and trustworthy He is, just how powerfully He loves man in
spite of our sin. His nature is actually described in 1 Cor 13 in its description of love. He’s anything
but the angry and distant God, aloof in His superiority, “jealous of His prerogatives” as the catechism teaches, which is our default concept of Him and which is the way
we generally play God whenever we tend to abuse power or authority over others ourselves. Jesus restores the “knowledge of God”.
Creation needs to know something of the existence and unfathomable worthiness and goodness of God-and of the undeniable truth of our need for Him. Adam refused to accept his limitations as a creature; he
“preferred himself to God and by that very act scorned him. He chose himself over and against God, against the requirements of his creaturely status and therefore against his own good.” (CCC 398)
Adam essentially dismissed God,
as God. But:
"Man is dependent on his Creator, and subject to the laws of creation and to the moral norms that govern the use of freedom." (CCC 396)
From the large perspective the entire drama of creation, through the Fall and up to today, is for creation to ultimately learn, the hard way, over time, and without force, its place, God having made His world in a “state of journeying to perfection” as the catechism teaches. In this way something better is produced, something more like Himself that knows for itself why true justice, defined best and most fully as “love”, is of such high worth. And He’ll finally have His way in this, by the end of the day.
