Thanks alot @oneray. I greatly appreciate you interpreting this. The law is what revealed sin and the knowledge of a 'law' is an evidence that your WILL can either keep it or break it. Adam and Eve had their will to whatever choice they wanted.
If the instruction was not given, they wouldn't have broken it. Agreed? Let me briefly show you how the law influence your WILL. Obey the command below.
