If you are saying that Adam was created without literal knowledge of "good and evil" and that God's command was therefore like expecting a dog to know the difference between sweet poison and sweet juice, then you are also saying that the other aspects of the text are literal too.
I'm just taking the story at face value. There was a tree of "knowledge of good and evil". At some point, if you believe this story as literal history, they ate the fruit. Ok, what did that act impart to those pre-humans? Was it the knowledge of good and evil?
Genesis 2:25 says they felt no shame before eating. Chapter 3:7 they became aware of their nakedness, felt shame. They had (v 5) began to "know good and evil".
So, before - no knowledge of good and evil. After, they are "like god" knowing good and evil. This is the story handed to us by JWs and other people who take this as history.
I was exploring what it means for a human (pre-human) to be in that state, and what it implies about their ability to take the "right" course of action. And what that means about the culpability of doing "wrong".
Everyone keeps focusing on the serpent, whether you believe it was Satan or not, as being so clever. Oh poor Eve. She was tricked, lied to, and now look at us. No, she wasn't tricked. She had no idea what was happening to her. She couldn't decern good from evil. She couldn't detect deception because she couldn't understand evil.
I compared them to a dog because without a moral compass there is nothing to guide self control, and even if they are incredibly intelligent, they would behave like dogs.
