What would you do?

I have a nephew like this, also his dad who is my uncle. The nephew beats up his mother (my aunt) for drug money, and my uncle beats up his mother (my grandmother) for drug money. If you ask the moms they will tell you that their children can do no wrong. I just let them be. They all seem to enjoy it. The nephew almost finished himself off, but didn't quite. Just a tad short of an overdose. You however do not seem to enjoy it, but you do fall far short of being mad enough to call them names, as you did for the cops. Legally you can do almost nothing, that will work. Anything I would suggest to you, like some you have already read here, would really be pushing legality to its limits. You probably wouldn't use the suggestions because a.) they are illegal or b.) they are relatives. I can hardly bear it when someone says that blood is thicker than water. I have had more relatives than I can count screw me, and they are not done yet. The most important allegiances you should have are to your wife to who you made vows, and your children who had no choice in their parents...untill they are adults. With my children, who are all fairly well behaved, they became adults when they said they were.
