Adam was created perfectly, in fact God hung out with him "in the the cool of the day". Eden was also created perfectly, for all the life in it, even the weeds. There was no bloodshed or suffering. God gave Adam and Eve the responsibility of caring and preserving it all.
But God, from back then even to this very moment, knows that forcing anyone to love him is not love at all. Adam and Eve would never be forced to choose God's side (neither are you). And, bad for us, they chose to believe that God lied to them about the knowledge of good vs evil.
I agree that it does seem severe to us, since after all Adam and Eve were kinda tricked. But God is outside of time. Nothing is severe to him. It's ok, call it severe, God knows it's hard for us. He is perfect, we are waay not.
So where we are today is where Adam and Eve were, allowed to choose God's side or not, to call him a liar or not. He's being patient, waiting for more folks to choose his side -- to simply believe what he says, regardless of what other people, or serpents, tell you about him.
(BTW, his patience must soon run out. Don't just look busy... believe what HE says.)
