I agree with dgrimm60 that this was the case
Ezekiel 28
15 Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee.
16 By the multitude of thy merchandise they have filled the midst of thee with violence, and thou hast sinned: therefore I will cast thee as profane out of the mountain of God: and I will destroy thee, O covering cherub, from the midst of the stones of fire.
Regarding the situation with Adam and Eve, I look at it this way.
Eve was told not to partake of the fruit. She did so against the clear instruction from God not to, however, she was deceived into it because the enemy put transgression of Gods commandment between her and something she wanted- growth. The enemy said 'your eyes will be open', implying that they were currently not. She wanted knowledge and growth, and those desires I believe are natural and God given, the enemy used this God given desire in a way that perverted it from being a blessing into being a curse, just like he does with every other natural desire that people have.
Adam, on the other hand, knew that he was transgressing the clear commandment of God, and it looks to me at least like he did it knowing full well that he shouldn't but did it anyway because his desire for his companion Eve was greater than his desire to follow the express commandment of God. I often wonder what would have happened had he refused to partake of it after Eve had.
