Desire and Innocence?

After reading John Milton’s Paradise Lost, we could easily perceive that it is an epic poem that aimed at portraying the story of the Fall of Man: the temptation of Adam and Eve by the fallen angel Satan and their expulsion from the Garden of Eden. Yet, I would like to talk about whether if the behaviours of Eva and Adam and the consequence they have are out of desire or just mere innocence.
First, we could find out that Satan is a skilful talker from his persuasion to other rebel angels and subsequently organising his followers. When it comes to the scene when Satan returns to Eden, enters into the body of a sleeping serpent and successfully tempts Eve by compliments and tricking her with his rhetorical skill. After being tempted, Eve eats the fruit of the Tree of Knowledge and takes some fruit for Adam. As for Adam, seeing Eve has made mistake, deliberately commits the same sin. He says to Eve that as she was made from his ribbon, they are bound to one another so that if she dies, he must also die.
From that certain scene, I would imply that the reason why Eva will eat the fruit of the Tree of Knowledge is out of curiosity and innocence. However, her curiosity could be seemed as desire that make people want to know discover more information. As for Adam, he is seemingly smarter and more rational than Eva. Yet, if he has no love and so-called responsibility for Eva, would he still eat the fruit that Eva has eaten, too? In my point of view, I would suggest that there is certain innocence in Adam as well as in Eva.
