Omniscience does though.

Edit: Just to expand on that, I think what you're saying is that the reason your future acts as an omnipotent being must be included for uncertainty is that otherwise present knowledge would allow perfect prediction based on causality. That's not quite right though - if an omniscient being's actions were reactionist then they couldn't be omnipotent, so there can be no emergent reason for future action. You wouldn't build a rock you can't lift, because that'd be a failure of knowledge. Please correct me if I've misunderstood.
