Being sexually assaulted would have been just one destructive factor, of more importance is that her childhood was stolen from her, that she was stolen from her parents, that she was confined in a small ‘cell’ for nearly a decade, denied an education, social interaction, access to fresh air, and that under just these circumstances alone she was brainwashed or institutionalized (Stockholm Synd.) and the continuing years of her life will never be normal or routine.
I cannot even imagine the first feelings of betrayal, hysteria, calling for her parents, calling for anyone to save her; and no one came. Even is no sexual assault occurred, I doubt that would have been much more than icing on the cake of Hell under the circumstances.
