You could choose to see it that way, but it's more than that, too. God...is a clumsy, emotionally charged word. The proper term is Kami, or in my case Myojin.

And you are both correct and incorrect. We're not lacking in free will in the slightest, we make and are accountable for our own choices. We are predisposed towards certain temperaments, and our powers cannot change. That is to say I could not suddenly become a god of fire if I wanted, but there's nothing to stop me from choosing to act in a certain way if I wish it.

We're no different from mortals in many ways, really. Which, if you consider that mortals all contain a piece of us, it makes sense. And the mortals around us influence us as much as we influence them.
