Doctrine of the Fall

The doctrine of the fall has had a spectrum of adherents, from some who think our fallen nature is a slight deficiency to others who say we are totally depraved.

“Why does God institute circumcision in Genesis, what’s that got to do with anything?”

Jonathan asked "Wasn't the ground over the whole earth cursed when Adam sinned so that thistles and thorns would grow, as there weren't any weeds before Adam fell?

When God said he was sorry that he'd made mankind because their thoughts were continually wicked (Gen 6) was he talking about the whole of the human race?

Doesn’t the arbitrary nature and bad behaviour of human beings rule out the universe being made by a good God?
