The Answerer

Quite simple really. God gave Adam and Eve a whole garden to eat from except for one tree. “Don’t eat of it,” He said, “Or you will die.” Spiritually they would die, not like being poisoned by the tree's fruit, but they chose to do wrong by disobeying God.

God did not post armed guards and force them not to do wrong, He gave them the choice to do right or wrong. They did do wrong and humans have been exercising that choice (to do right or wrong) ever since. It does make those who do right shake their heads in despair pretty often (I think TV causes some of it).
