You asked about how all of humanity could be so screwed up, and this is why. Evil tends to propagate evil, individually and societally. And this is part of what is meant in Christian theology by “original sin.” The message of Scripture, Dad, is that we are all, individually and collectively, too far down the road to now “make ourselves” what God intended us to be. We can’t, on our own, make ourselves right with God, with each other, and even with ourselves! We need a new start, a new creation, a clean slate. And this, according to the gospel, is what God has given us in Jesus Christ.
