EWTN has a Q & A answer by Fr. John Echert which deals with several aspects of how the story of Adam and Eve may be viewed
HERE .
As the answer develops , he says :
And while there is latitude as to the literal nature of every detail of the story of creation, the Church teaches that we are all descended of an original Adam and that original sin is transmitted in the process of generation.
For the sake of argument, let’s say that we are following a
more literally confined path along the story of creation. One of the first things I notice, is if we follow the sequence laid out in Chapter 2 of the Book of Genesis , God told Adam not to eat from the tree of the knowledge of good and evil
before He even forms Eve - his partner. [Genesis 2:16-17]
So the imputation of responsibility is initially placed directly on Adam . . . which subsequently concurs with St Francis’ post -
My understanding of this is that Adam should have been protecting Eve, not following her into sin.
Personally, I have always struggled when trying to view the entire scenario of the Fall as two separate sins - one of Adam , and one of Eve . While they both surely did sin and equally bore the guilt of the sin, we can’t ignore the high degree of complicity. I see it more like they participated in the same sin ; (if you’ll pardon the expression) partners in crime.
Look how closely together the Book of Genesis places them at the scene of the crime :
Genesis doesn’t say, “Well, the woman sinned and fell . . .and then later when Adam got home from work (he didn’t have to
work yet either

) . . .” Rather, we read in Genesis 3:6 -
So she took some of its fruit and ate it; and she also gave some to her husband, who was with her, and he ate it.
If we further consider that just prior to the Fall the souls of both Adam and Eve - created in the divine image, were still imbued with original holiness, justice and free will , and that they were in a harmonious balance with God and nature ,the plausibility that they basically participated (shared) in the first sin at almost the same moment increases.
Trying to claim that Eve sinned and then caused Adam to sin, places the two of them just a little too far apart - and in my own limited opinion, that particular approach has never been able to pass the
Mom God Scrutiny.
