What was Augustine's approach to the Problem of Evil?

Augustine described evil as being a privation of good, that is it say that evil is not actual. When God created the world, he made it perfectly and evil did not exist, yet the Fall in the Garden of Eden led to the disordering of human priorities therefore disrupting the balance of perfection and all that is good in the universe. 

Augustine maintained that we have a choice as to whether to be good or not and whether to love or not, known as Augustine’s Soul-deciding Theodicy.
