No, it doesn't. That's like saying technology can create souls because we have test-tube babies.
And Jordan did not answer that. He did not say the makers drew them from the pool or that the One Power is still used to bring forth each generation of Trollocs. That Trollocs reproduce on their own suggests what I said before, that the makers of those creatures merely simulated the conditions under which sapient life begins. There is no direct evidence that they reached into the soul pool, grabbed on and stuffed it into a body they made. They used the One Power to mess with the biological processes and make their constructs come out the way they wanted.

No. It is the ur-state of existence. As Verin explained to Egwene, it is the third constant, along with the Creator and the Dark One. To me, TAR is like the base substrate of creation. If your soul is able to project yourself there, you have Creator like powers (limited by your strength in the Dream). "Reality" is, basically, the Creators dream, melded to TAR (or dreamshard, as Brandon Sanderson called it. Stupid as that name is, I'll stick with it for convenience). Rand, in Shayol Ghul, was creating fresh Dreamshards in his contest with the Dark One, both of them re-writing the rules of reality as distinct from what the Creator has set.

They go there in their non-corporeal bodies, or live in T'A'R bodies, whatever. You can't see a soul. If you can, it isn't and RJ is misusing the word to describe something else.

It explicitly is not. Trying to change what the books to fit your worldview is a little bizarre, Cannoli. So what is in T'A'R is not real? How so?

Yeah, it is stupid, but it's what we have to go with. But if souls aren't souls, the people in WoT are not people.

Because that's all SELF-directed changes, not externally imposed.

Because the point is that you grow and change into what you will. If someone else can alter that, your own efforts are rendered meaningless.
Well, Ishamael is closer to Buddha's view than anyone else in WoT, he just didn't see the solution that Gautama did.
Because it means someone can change who and what you are.
We don't know the process of corruption. It's at least possible in the story (and only possible in reality) if the person is made corrupt by their own thoughts, actions and choices, and so becomes susceptible to that sort of transformation.
It really was a sidebar in my stream of consciousness as I wrote my original answer. I was thinking about what the Dark One could do to one's soul to make them into a Gray Man and I came to the conclusion that he couldn't, or it's not a soul.

I don't think the One Power is the essence of creation, or there'd be more of a will power component to it. I like your explanation of T'A'R better for that. If the Power had something to do with how Creation was made, it would be used more like people do things in T'A'R. I think the Power is a primal force made to MOVE creation, like fuel or lubricant or blood, but it's not the mechanism of Creation, or the creative force of reality. If for no other reason than you can't really create stuff with it, only shape what's already created. That makes it just another normal thing. Given how the One Power compares and relates to the Shadow, it is not the Creator's equivalent of the True Power, or if it is, then the Dark One is missing a balancing force and he is NOT the antithesis of the Creator. The Creator made the world and moved on and did not leave his own personal toys for the inhabitants to use. The One Power is of the world, not the Creator (except in the sense that everything he made is of the him, including the world & One Power).
