Was sin necessary for knowledge?

[Catholic_Lady]

It's hard for me to answer this because I don't adhere to the literal interpretation of the Adam and Eve story. I think we evolved from apes, and at some point we became intelligent enough to understand right from wrong. That is when sin became a thing. So on the contrary I would say knowledge is necessary for sin. Animals are innocent because they don't have knowledge of good and evil and therefore cannot sin. We evolved from animals. At one point we couldn't sin, but as we became more intelligent, we obtained moral culpability and thus the ability to sin.

This is kind of a rushed response because I'm in the middle of stuff as I'm posting, but hopefully it makes sense.

Sorry I didn't take the time to get caught up on where we are. IMO to the OP question: Was sin necessary for knowledge?
I would answer no. Sin is not an object, state or a place it is defined as "a transgression of God's law". Therefore knowledge is necessary for sin, but sin isn't necessary for knowledge. You would need a law or something to transgress against to be able to sin.

Hah, I made my response that knowledge is necessary for sin before I read this. 

Great minds! I like you already.
