I think the fundamental difference was that she transgressed and not sinned. There is an important difference.
Given the commandments to multiply and replenish the earth AND not to partake of the fruit meant that you either obeyed one or the other. Couldnt have children without falling, and couldn't keep the command not to partake if falling and having children.
Eve as one of God's finest daughters made the decision to bear children and get the knowledge of good and evil so as to progress through choice, rather than stay in an 'infant' and innocent state.

God knew who He had put there, and knew they would make the right choice for all His children. Now all his children have the ability to progress and choose to return to him or not.

Adam and Eve were our first parents for a good reason, they were some of the greatest of all time, and to reprimand Eve for her brave choice I believe is unwarranted.
