A young man about 12 years old really impressed me with a question that had him baffled. It demonstrated what a deep thinker he is. He asked, "If Adam and Eve were perfect, wouldn't their perfect sense of justice prevent them from disobeying their Creator?"
Going to the source material is always the best solution in these matters . Genesis 3:4-5 explains why justice got skewed in Eve's mind. She was told by “the serpent” that God had been unjust by preventing her from reaching her full potential. The serpent (a guise of Satan) had Eve so cunningly and thoroughly deceived that she may have even thought to herself that even if she asked God whether the charges are true or not, she wouldn't be able to trust the answer. In her mind, God's truthfulness and justice were in question. Therefore, being disloyal to a God that wasn't truthful to her was no longer an issue. In other words, since God was unjust in preventing her from achieving her potential, then she didn't feel she owed justice and loyalty to God.
Compounding the issue, after Eve ate the fruit she didn’t die on the spot, so when she gave it Adam, she may have said (although there is no record of it in scripture), “Hey, I ate it and I’m still alive.” Sadly, she was blatantly lied to by Satan and then she allowed personal (selfish) desire to enter the picture.After their eviction from paradise, they were treated just as a parent who rejects a wayward child, “You are dead to me.” Indeed, Jehovah God treated them both as dead, never again speaking to Adam like he did in the garden.
In reality, there were things Eve could have done to verify any doubt she had. But the account is quite plain as to what the real reason was for her disobedience: Eve “saw that the tree was good for food and that it was something desirable to the eyes, yes, the tree was pleasing to look at. So she began taking of its fruit and eating it.” (Genesis 3:6)
