Sometimes (at least in principle) God might allow some evil because doing so will prevent a greater evil, and sometimes He might allow evil because it will produce a greater good.

An alternate explanation is not a refutation.

Something good made something bad possible (though not inevitable). Humans, however, didn't use their freedom well. Instead of using it to honor God in friendship, they used it to rebel.

Our souls - our invisible selves - bear the mark of God Himself. We're like God in that we bear His image.

Man had freedom to choose the good, but this same freedom also allowed him to choose the bad. This is called moral freedom.

In the Story of Reality a man is a helpless slave - enslaved to his own passions, the flesh, and enslaved to a cruel master, the devil - a slave who God Himself rescues and adopts into His own family. It is the very worst news coupled with the very best news.

Cursed is everyone who hangs on a tree.
