Right -- immature and sad, then kidnapped, abused, and tossed in the trash, rather like some of our serial child molesters might do.
The rule in America is that the "child" (one falling into a specific age range stated in the law) is not to blame for the abuse. The "guilty" party is the "adult" who should know better. Granted, Diana would have been outside the legal limits, but the characterization is basically correct.   
Sorry, I understand that the Royal Family's historicity makes them valuable to you folks, but I'm raised to believe no one should have the kind of clout they have to do stuff to their own citizens.
I don't just criticize your gov. -- I know who my own representatives/senators are and maintain contact with them and try to stay informed here. And I vote.   Tw
