You know, I took Asian philosophy in college, because even though I am a Christian, I think most world views have at least some wisdom in them. And this situation reminds me of something Confucian:
Confucius said that all of our social relationships in this world; village, state, country, business, etc. are all based on our family relationships. Since the family social structure is the one we are born into, it is the most powerful. Therefore, if that structure (the family bond) is not functioning as it should, none of our other social relationships will work either. I think that applies pretty well here. These kids didn't have many friends because they were treated badly at home. Anyway, i don't know for sure of course. But yeah, those are my thoughts.
