Look, Casca's mind snapped from what happened. It's a coping mechanism of the human body. It clearly means Casca couldn't make the decisions she would have to make after what happened to her. She didn't lose her mind from the rape, but from the mental trauma and the stress of accepting what was happened.
For Casca to remain mentally stable after that she would have to have a completely different personality all together. I would expect revenge or passive acceptance of reality from someone who has had a less traumatic life and cries less.
Basically, if she comes to, she can't be her bitchy old self, because it was that personality that is broken, dribbling idiot right now. She has to change dramatically to first accept the experience in the eclipse, let alone, join Guts in fighting apostles. I'm suprised Casca doesn't run just at the sight of monsters now. Guess she doesn't relate them to sex in her current state, so that's how she survives.
