Yet, even though freewill is expressed in a way that is not determined by God (or it wouldn't be free), it is allowed by him and it's exercise sustained by him. It reflects his will for the way things should be, and without such concurrence, it wouldn't be. If that is so, how can the same difficulties which determinism suffers from in regard to the problem of evil not ultimately be true for freewill as well? If God, the omniscient and omnipotent, proceeds despite evil he could foresee or does not stop what is proceeding against his will, there would seem to be a problem with evil after all.
I don't think that is so two reasons. First, God is good, and making something in his image just could not be evil by any stretch of the imagination. Even among human beings, we consider it good to have a son or daughter, even though we know they will do things that are bad. The beauty of being made in God's image is an amazing thing, human beings are amazing creatures. That God would want to make us in his image, able to will as he does and love as he does, is a remarkable demonstration of benevolent grace and something that properly could only be said to be very good.
Second, evil isn't being allowed. It's only the perspective of the current regimen of time that makes it seems so. Death and entropy themselves are arguments against evil being allowed, revealing that God has pulled the plug on this fallen realm of fallen beings. Within our bubble of time we may think evil is allowed and that it's been going on forever, but from God's timeless perspective evil is being dealt with virtually immediately. In this realm's wake, after it's been flash-burned in a cosmic reboot, evil will be something not likely to be even vaguely remembered.
