A perfect god creating a Perfect Eve would know that she would make Her decisions true to her God given nature.
The fall then becomes a leap towards the proper path.
Not a fall but a glorious leap towards our quest for knowledge.
God wants us to know the tree, that's why it is there and the fact that He has allowed us to eat of it for all these years is a clear indicator that we are doing His will, otherwise He would have ended a failed experiment years go.
