I don't believe in God as a thing that creates others.
I can see it/her as the "place" we all come from and it's the centre of the Energy we are talking about.
It's not then a question of creating some souls "weaker" than others" but just to have a natural diversity without a specific plan.
Besides, what we are trying to identify is probably still nothing and what appears to be stronger, might even mean weaker if seen from a different perspective.
