Most of the kids in that compound wouldn't know that. They've been told all their lives that this is God's will and that the outside world is evil and of the devil. That has effectively stopped any chance they have of reporting it. They're not like the kids outside the compound who are taught that that option exists.
Your constant blaming of the children for staying in their abusive situation is disgusting beyond words.
The parents are responsible to make the abuse stop. It's their JOB to protect their own children. That's why God gave kids parents, to protect them when they are unable to protect themselves.
NO, NO, NO, a thousand times NO!!!! The children are not the ones responsible to stop the abusive situation, it is not their burden to bear; it's the parents responsibility. And if the parents won't do it, someone has to and the government is the only body left with the legal authority to do something.
Blaming them for something they have no control over is abuse in and of itself. That's just adding psychological abuse in the form of a guilt trip on top of all the physical abuse they've suffered.
I am saying that kids, in an abusive situation, must make a personal choice.
If they report it to a responsible adult, then the police can get involved. The police can then gather evidence, which may be used in a court of law to convict the abuser.
If they decide not to notify an adult for help, then that was their personal choice also.
