The tree was in the midst of the garden, along with the tree of life. So, I have to assume that there is good reason, I'm not questioning that. What I do question is the common understanding that it was placed specifically for the testing of the Adams. God created the world "and it was good," so then wasn't the totkogae good? The is scripture of God telling Adam, before He formed Eve, "you," second person singular masculine, and there is no scriptural account of God saying "ye", second person neutral plural, so it just makes me wonder at the hypothetical consequence if Eve ate and gave it to her husband, and he did not eat, would have life in the garden then continued without much consequence? Was it meant for anyone but Adam, since he walked with the Lord and had One greater than the tree?
Sure, this might be an example of an exercise in futility that @Cameron previously mentioned but... just some things that nag at me at times.
At any rate, the ultimate result in the drama is that everyone now has access to One greater than the tree.
