I mean, you are kinda wrong, but for the "wrong" reasons. It is true that at the moment this entire problem may be a plan of original CJ (Glory), and that he actually planned for the four to kill Jacob, create an imaginary replacement made out of their desires, preferences and fetishes, put that imaginary being in a human body and gave him dead jacob's shard of himself, but even if all of this is true and is all his plan, that still makes CJ a creation that at the moment is being controlled by the 4.
Glory could have planed that they would make CJ, but that doesn't mean that CJ is free or in control right now. He may be in the future when glory's plan comes about but until then CJ is still a toy of the four. For example: If i had a plan to make me rich, that doesn't mean that I am rich and that I can buy everything I want right now, I may be rich in the future once my plan succeeds but until then I am dead poor, same with CJ, until whatever glory planned for him happens, he is a toy of the four, regardless of if this whole scenario is for him.
Even if glory created the four, it was the four who created CJ, that is this whole arcs plot. And you can't just say that because glory may have planned this or may have created the goddesses he is CJ's creator, that's like saying that my grampa is actually my father, since he made my father, or like saying that if I created something new that new thing would actually be my father's creation, since he made me. You are stretching the correlations too much.
