Dr. Craig is a liar.

Evil, then, is the act itself of choosing the lesser good. To Augustine the source of evil is in the free will of persons:

And that is my problem with the human description of the alleged gods in the monotheistic religions. The god is always described as all powerful and all knowing*, yet when anything bad happens, it happens because god gave people free will and cannot interfere in their free will.

The first part is flatly contradicted by the second, because if god cannot interfere in others' decisions and actions then he is neither all powerful (he cannot stop them) nor is he all knowing (he cannot know ahead of time what they'll do). It blows the whole of the main christian apologetics argument against the problem of evil out of the water.

* You also cannot have an all powerful and all knowing god, but that is a whole 'nother can of worms that monotheist apologists have failed to adequately answer.
