The Eden should not be the Earthly Paradise, but a parking where Adam and Eva were very bored to the point that they tried a new way, the one the loss of the innocence by the discovery and the cognition of the difference between right and evil, those, however, pre-existed. The Angels changed in demons very knew the abysmal difference.
Since here, more or less we can read and interpret in the Bible book (Genesis): facts notified by the author Moses.
That was not a conquest, but a fixed way, so that man could built a conscience, by rationality and its contrary: the sexuality, that is stimulated by the irrational passion. On the other hand we cannot think the Creator would form man only because he was left alone for ever with his partner in a contemplative and childish condition. The innocence was not him eternal destiny. Why the Creator would allow the other beings multiplied, forgetting his creature so favorite to do it like him?
I think Creator would know since forever man would prefer the dynamic suffering of cognition than the immobility of the innocence, because He created him destining him to the freedom, that is just the option to choose between good and evil. But God, who is the absolute freedom, even if He knew the choice of man, He did not interfere to avoid the evil that man would make to himself. The “do man in our own image” has a meaning if we express it like “do free man. To him the use of freedom”. We could explain so the promise after the original sin to send a Savior, that is the Son and by Him the same Father. Creator did not abandon the favorite being and so the mercy was born, that has a sense only if it is turned to the fragile human being. God knew and loved and allowed (but could He not allow?) the sacrifice of the Cross and the Resurrection to crowd in the same the man delivered by the consciousness, but on the condition that the choice between good and evil would fall on the first. Maybe this reflection allows to interpret, from a different point of view than the traditional one, the assertion of John Evangelist (cap. 8,32) «You will know the truth and the truth will make you free», that clearly means that the freedom is a consequence of the truth, that in its turn, requests its knowledge.
Here is the meaning of the freedom and, even if the hands of man pour blood of the evil, after all the hope is in the victory of the good chosen freely, because it reaches the merit of the trial of its line.
