"Her choice made all other choices possible."

This makes sense to me as a definition of beguiled

While I am unclear on the meaning of the word beguiled, I have been led to the meaning defined in the OP as I have watched and pondered the current films in the temple. Whether or not Eve knew what she was doing in eating the fruit. Her doing so allowed for the existence of us all in mortality and our agency here.
