Riddles are much more difficult to solve when you begin from the completely wrong conceptual starting point.
Just like the opposing conclusions that conservatives vs liberals reach on every topic,
when you start from an invalid premise (ie, a lie),
you’ll always come to an errant conclusion.
“man is basically good” gets you liberalism, ie, error.
“Man is a fallen sinner” gets you the correct conclusions.
Both sets of conclusions are logically arrived at, but from different starting assumptions.
