Why does God allow things to get so out of hand?

And again, the answer must go back to the foundational issues. If humans were designed to be corruptible, sin must be a possibility. If sin is a possibility, oppression will exist, eventually on a large scale. If God were to wipe out the possibility of oppressive tyrants, he would have to wipe out sin; and to wipe out sin, he would have to eliminate corruptibility. If God were to eliminate corruptibility, we would be nothing but robots. That has not been his design. 

 God’s procedure throughout these early chapters is generally not to eliminate the problem totally, but to isolate, limit, or restrict it in some way.
