A proposal for a better world

In one of your lectures, you said as an answer to the problem of evil, that whoever claims that a world with fixed laws of physics + free choice can exist that is also better than this world has the burden of proof on him. That is, we can assume with a fairly high probability that if we want to combine free choice + fixed laws of physics, our world is the best. That is, God wanted to create a good world and the fact that there are earthquakes and volcanoes is the lesser evil. It can’t be better than that.

Now I want to offer a proposal that brings a solution from another direction, specifically from the direction above physics.
A world where only one person (or some people) has a soul. Everyone else is soulless (this doesn’t mean they are necessarily evil or immoral).
What does this solve?
The people who have a soul are people who were “dealt good cards,” or at least neutral ones. They weren’t born with a serious illness, they weren’t born poor. They were born okay. In an environment that is okay, and now we can examine their freedom of choice and see how they will behave.

Such a world is necessarily better, because babies born only to die have no soul and no consciousness that suffers, as do all people born into a reality of necessary evil.

If you believe that God created the best world possible, then in my opinion you should adopt such a model of belief.
Especially given the fact that I have no real indication that people other than me have souls.
