Vampy,
I do understand your point, but in the Garden of Eden, Adam and Eve was given everything that they would to be happy with, God tells them that there is one thing that they cannot do, just one. It's different from us being parents because we have a lot of dangerous stuff laying around that should be out of reach from children, But God only had one thing, which was the tree of the knowledge of good and evil.
We the parents tell our kids not to use drugs, When our kids do cross over the line to experiment, What would happen if they did an experiment? Anything could happen, an accidental drug overdose could happen, who's fault would that be, who would be at blamed? the parents? no the person who did the experiment.
