For the time being, we can't say.

First, we should note that Aizen has a God complex.

I believe that when he got the opportunity to see the Soul King, he got disappointed because he found the ruler of Soul Society to be a despicably weak being who didn't deserve to be what it was. And so he reinforced the idea that he was special he deserved to be God.
