Free choice and souls

peace,
If we assume that free choice exists, then each of us is a soul with free choice.
The question arises: how are these souls created and what is the difference between them?
If there are souls that were created better or worse than others, then there is also no real free choice, because a soul is a duplicate of the qualities with which it was created. One soul was created this way and another that way.
If we claim that all souls are created equal, then it means that each of us would act in the same way if we were in a particular body at the same starting point.
Let’s take a person who murdered and say that in a deterministic world there is nothing to be angry at, because he was bound by reality and was obliged to murder – if we add to this that a soul exists, we have not solved the problem. Either his soul was created “worse” than others and therefore he murdered, or his soul is the same as others but reality obliged him to murder.
And if we assume that souls are created randomly with random laws, then souls still operate only by necessity of the random mechanism that generates them.
I would appreciate your feedback on the matter.
