Honestly, the worst possible outcome would have been for the abuse to continue. I am not a fan of splitting up families, but the mother has failed her daughter by telling her to keep the secret. I praise the older sister for knowing the right thing to do.
Do I think it’s possible she will find more happiness if the abuse has been stopped? I believe she has a far greater chance to. As for her mother being in jail, that will be up to a judge to decide, and the judge knows many more facts than we do.
In regard to her 11-year-old brother? I wholeheartedly believe that it is right for him to be held responsible for his actions. If it had been kept a secret - especially at his age, especially knowing that there are adults that would cover for him - he would be way more likely to continue the assaults, and perhaps branch out to other victims as he continues to age. I hope that now he gets the help that he needs to stop his abusive behavior, and learn proper behavior instead.
It appears pretty clear to me that they all need a lot of help, frankly. I’m a fan of reunification of families that have “lost their way” so to speak for various reasons. However, not if that reunification puts a victim at more risk of abuse or retribution for doing the right thing - which was to tell.
The brother will not be held responsible for his actions; that much I know for sure. That is no longer the ‘American way.’
