They did "their will" and chose the tree of knowledge of good and evil.
Genesis 2:9
"...In the middle of the garden He ( the 1God) placed the tree of life and the tree of the knowledge of good and evil."
Adam & Eve decided to do "their will"...and so they chose to take of the tree of knowledge of good and evil....to define good and evil in their own eyes for their self interest desires.
How powerful was this desire to do "their will" that it caused them to NOT choose the tree of life?
This is what both the Republicans and Democrats believe in.
This is what the nations of the world believe in and worship.
