Ok, I have not understood you question.
Have you read the sutta “SN 44.10 With Ānanda – Ānandasutta” that I have put it in a file in the post " Attā and anattā real meaning reveal in the sutta " that the Buddha did not answer questions from Vacchagotta on whether “does the self exist absolutely?” or “does the self not exist absolutely?”.
That is to say that the Buddha did not approve of a “self” (in your case “soul”) and also did not disapprove of “no self”.
Your misunderstanding arise in post 25 with the question of “Why is atta equated with control?” The reply was that there are four interconnected senses of atta or anatta. If you have atta as “self” (sense 3) , you will not have “with control” and if atta is “with control” (sense 4), you will not have “self”. Both “self” and “with control” for atta do not exists at the same time.
