Was sin necessary for knowledge?

[A Theist]

Surely that just means that sin was only necessary to obtain knowledge of good and evil, not knowledge itself.

Didn’t Adam name all the animals? That implies he had the knowledge to do such a thing.

In the New Testament, the Bible says in one place, (I Corinthians 10:13), that God is faithful who will not permit us to be tempted above our ability to bear. I would imagine that would also apply to God giving a command and the ability of the person to understand, and to obey, and to carry out the command given. My thought would be that both Adam and Eve knew exactly what God commanded and that they both understood that disobeying Him would be wrong. I think that both A&E had a knowledge of sin that was limited to what God expected of them. I believe that Eve knew it was wrong to listen to the serpent but she was tempted by the lie he told her. I believe Adam knew it was wrong to allow Eve to talk him into eating the fruit when God commanded them both not to. So, I think that both A&E had a knowledge of sin that was limited to only what they understood at the time before they ate the fruit of knowledge of good and evil. The fruit only broadened their knowledge to more sin.
