No -- but you did exercise that freedom of choice when you rebelled against the word of God like she did and sinned.
Nevertheless, Original Sin still entered the world. The act of disobedience brought forth death - Mary's act of obedience brought the Lamb who conquered death into the world. God doesn't operate a Heavenly Democracy - He appointed Mary to represent us, and she did her job perfectly.
Sorry but your theology is flawed. Scripture does not say that sin entered the world through Eve but through Adam, and it was the representation of the Second Adam, the Son of Man, that was effectual for us, but only for us who believe it -- not for those who believe He needed a Marian co-redeemer or co-representative.
It's either Jesus as your representative redeemer or Mary -- exercise your freedom -- make your choice .
The woman saw that the tree was good for food, pleasing to the eyes, and desirable for gaining wisdom. 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. Then the eyes of both of them were opened, and they realized that they were naked; so they sewed fig leaves together and made loincloths for themselves. ~ Gen. 3:6-7
What is the act of sin?
not for those who believe He needed a Marian co-redeemer or co-representative.
"Co-Redeemer" is a Half English, Half Latin bastardization of the theory of Mary as the "Co-Redemptrix". You've got the Redeptrix = Redeemer part down, but you are confused as to the "co-". From the Latin "con," meaning "with" - quite literally, for nine months, Mary was "with" the Redeemer. She co-operated in the Redemption of humanity by saying "yes" and being obedient to God, unlike Eve in the passage above.
Jesus came to earth through Mary, period. That was her ‘job’ and nothing else. She birthed him, raised him, and that’s it. She doesn’t have any special grace to be our co-redemtrix or anything else. She was an obedient young woman whom God blessed with the birth of our Lord. For that alone she should be recognized.
