Hi Bryan, this is a topic I would like to see explored sincerely too. I'll give you a hand to get thinking about it by sharing the POV I have.
The new earth after the final judgment will not have a serpent, and everyone who is part of the resurrection into Christ will have endured and overcome the serpent, thus we will have experience under our belt that Adam and Eve didn't have. In my mind, those who are part of that resurrection will be 100% loyal to Jesus Christ (see
Matthew 7:21). Therefore, there won't be anyone there who will disobey God again.
I think the whole process of life is meant for learning with the biggest lesson being to listen and obey what God says, not just because we are afraid of being punished for disobedience, but because we know that He alone is the absolute source of wisdom and anyone who disputes what He says is a liar. This is why Jesus describes Satan as a liar and a murderer (see
John 8:44).
Another thing you have to keep in mind is that we can't blame Satan for everything that goes wrong in the world, because it is human sin that causes the problems, the humans are given a conscience to know what is good and what is bad, and the angels and demons use the conscience when they are manipulating us. It actually takes a conscious effort to dampen the conscience but once a human has trained themselves to ignore the conscience they are capable of even killing their brother. This is why the human was forbidden to eat of the tree of life and live forever. To put it simply, a sinful human is a hideous monster. A truly repentant human is worthy to be Jesus' disciple and to have eternal life because we only ever seek to please God.
Well I hope this gives you a good start, please do comment on what you find interesting or even to ask for scriptural support if you find it is lacking, it is paramount that we hold the Word of God as the absolute authority on these matters because people often get all kinds of wild theories and there is no guarantee they have originated from God, I'm sure you know what I'm talking about.
