Natural suffering is not chosen
Privation and free will do not straightforwardly explain earthquakes, disease or severe suffering experienced by those who did not cause it.
Late antique philosophy · 354–430
Augustine explains evil as a corruption of good produced by disordered willing, not as a rival substance created by God.

Augustine of Hippo was a North African Christian bishop, theologian and philosopher born in Thagaste in Roman Numidia. His writings on will, time, memory, evil, grace and political community profoundly shaped Latin Christian and medieval thought.
The question he enters
If everything that exists comes from a good creator, what kind of thing can evil be?
The central move
Augustine denies that evil is a positive substance competing with God. Evil is privation: damage, disorder or the absence of a good that ought to be present. Moral evil arises when created wills turn from higher goods towards lower goods in the wrong order.
Key ideas
Where the view strains
Privation and free will do not straightforwardly explain earthquakes, disease or severe suffering experienced by those who did not cause it.
Divine knowledge, providence and dependence on grace create pressure on the claim that created agents are fully responsible for turning away.
