What is the Problem?

The biggest problem with theistic determinism is that it undermines morality as we know it. It appears to dissolve all grounds for holding anyone responsible for an action, good or bad. For example, let us suppose that God knows that Ade will assault the president tomorrow. Well, when tomorrow comes, Ade cannot avoid assaulting the president. Why so? Well, if Ade could avoid assaulting the president, it would mean that God did not know correctly, putting his omniscience in question; this is not a logical possibility.
