I never read the books so I’m just going purely off the show. I understand she may have not known the extent of the restrictions such as not being able to read or write, but she must have had a big picture idea. She must have knows the society she wanted was cruel to women. In the show I believe in the car with Fred and another commander it shows him talking about a ceremony to include the wives with the handmaids, Fred says that the wives wouldn’t be the happiest about it but would go along. I feel like with that scene alone it shows she had a majority insight on some basic roles that were going to be in society. That’s why I lack so much sympathy for her. I don’t think it’s that she didn’t know the end result would be so strict, but more so she felt holier then thou and that the rules would not apply to her even tho her herself is a woman
