The premise of the OP strikes me as self-contradictory. I can conceive of no way of establishing that there is an entity that knows everything, nor of wondering which, if any, mental proccesses such an entity would have.
Basically, either you believe that such an entity may exist or you do not.
So I do not see the OP's questions as truly useful, or at least I do not align with them enough to see the answers as more interesting than the fact that the OP bothered to ask the questions. I am now wondering why he did.
All the same, I do not see attempts at establishing the limits, attributes or mental and moral frontiers of an hypothetical God entity as generaly futile. On the contrary, I have engaged on them myself to the point of firmly establishing to my own satisfaction that it is not at all possible for God to exist and to dislike atheism. I also decided that if god exists, he cares little if at all whether people follow "the right religion", because even by human parameters it is all too clear that being an adherent of a specific faith is simply not important.
The bottom line is that I fail to see a point to the thread, but that only shows that I have a hard time understanding the point. It may exist and be too unusual for me to understand.
