Okay listen here, before God created Adam and Eve, He created angels, He also gave freedom of choice to the angels too same way he did with Adam and Eve, Most of those angels were good, did choose to follow God, But other angels made a bad choice that would be Lucifer and his followers so Lucifer and his followers were kicked out of heaven, Lucifer name was changed to Satan.
Adam and Eve should have been grateful for life and happy in their freedom, but freedom to choose does not bring happiness when bad choices are made.
God said, "You must not eat from that tree.(The Tree of The Knowledge of Good and Evil) If you do, you will die."
They both end up eating the fruit, Doesn't matter why it was planted there, You make a choice in life between right and wrong, between good and bad God gave us free will, We should be happy we are not slaves, We have a freedom of choice to do what's good, or do what's bad, If you chosen bad, You choose that path. God didn't tell you to choose that path.
It's takes an intelligent to know that he/she is responsible for their own life, choices they make in life all it takes to open your eyes to realized it.
