I'm becoming very troubled by what I'm reading here, on multiple angles.
First, I'm troubled because if the abuse is deeper and more widespread than we thought, and isn't just external bullying (which is way more than enough on its own, of course), then that's just sad, and I feel for everyone involved. However, a desire to protect your abuser is, for some, a natural outgrowth of victim behaviour. It happens because victimhood, painful and awful as it is, is a known commodity. It is something that is relatively well-understood, and if not precisely safe, it's at least familiar. Taking a wrecking-ball to it (which is what you're trying to do at the moment) is bound to produce bad results.
And that brings me to my next point. I have to say this right up front, and you may not like it. In fact, I can almost guarantee that you won't like it.
Zarvox, you are not a social worker, a child services worker, a mental health counsellor or anything else. You are, as far as I understand it, a high-school student who is enraged, sickened and disgusted by the abuse you're seeing. You want to help, and that's extremely good of you, but you are frankly not in any sort of position to decide what the best course of action is. Your prior posts in this thread have proven this beyond any shadow of a doubt. If you have been telling anyone that the only way forward is foster care, you are hugely overstepping yourself. It may be the best course, when it comes down to it, but you are not the one to make that qualification, and upping the ante that way and mentioning details like that is a really surefire way to get everyone involved to clam up. Who, after all, wants their family to spontaneously combust?
This is why there are people who go to school for interventions like this, and why it takes years before one has an appropriate touch. Your job, as a sort of civilian first responder, so to speak, is to help the people involved inform the appropriate authorities (school, parents of bullied woman, police, perhaps). That's it. Whatever happens from there is out of your hands. I cannot stress this enough. You do not have any means of saying what should or should not happen. You're entitled to your opinions, of course, but your opinions don't mean much, and shoving them on anyone at this stage is just going to make everything ten times harder.
My advice: talk to your friend, the one who's been bullied, and coordinate with her on getting adults involved. Adults outside the family to which the bully himself belongs, I mean. That is your sole area of responsibility at this stage. You are not a white knight. You are not morally obligated to save anyone. The more pou push, the more damage you will do. Please understand that I'm not saying any of this to spit on your attempts or to make you feel bad, but I am likely around twice your age, I'm studying social work, and I have seen and been part of numerous ugly situations in the past. I have the experience, both in and out of the classroom, to back up what I'm saying here. You dn't. And it's okay that you don't - nobody knows everything, not even by half - but please, please, cool your jets and take a few big steps back. Do what is truly best for these people. Don't just rush in and do what -you think is best. There is often a difference. You have let your anger and your outrage get in the way of good sense, but it may not be too late to fix things if you're careful.
