Actually, we can't, because Nicole wasn't doing things designed to break Eric down psychologically--in fact, her motivation was entirely the opposite, and she did not engage in a pattern of behavior designed to make him feel like he was so worthless that he wouldn't function normally. Eve might not have planned for JJ to get with her in bed, but when he showed up 99% broken down thanks to what she had done she decided to seduce him.
Saying that it wasn't premediated for Eve to try to break JJ down psychologically when she decided to "work on JJ" when Paige believed him about Jill makes no sense, in my opinion. Her whole plan was to do just that, even if the seduction wasn't originally part of it. That's what makes it not as simple as "he didn't say no, so he consented."
