That reminds me of the situation my own mom is in, actually. Out of six of us, everyone we know would say my mom raised all incredibly decent kids, except for one of us. My second to youngest sibling, at 15, has SOMETHING SERIOUSLY WRONG with him. I would label him as a sociopath no questions asked, and yes I know his background and his situation and everything else because I grew up with him for some time. He hurts my mom's dogs on purpose whenever nobody is looking (I've seen it for myself), he has told my littlest brother (8) to go play in the road on his bike right as a car was coming MORE THAN ONCE, and one time he led him as far into the woods as he could and then ran away and left him there hoping he would stay lost. The poor little guy didn't find his way home until hours later, crying when he got there. He steels constantly, from all of his siblings, from his friends, from his school, everything. Every word that comes out of his mouth is a lie. When you try to talk to him in the most serious manner that would get to any normal kids heart, he doesn't even pay attention. He'll stare straight past you waiting for you to be done, and once you shut up he says "ok" and goes to his room or whatever. You can take ANYTHING and EVERYTHING away from him in punishment (my mom doesn't spank or use physical punishment, but sometimes I inappropriately wish she would beat the crap out of him), and he doesn't even show emotion. He never cares. He shrugs, and a lot of the time does it anyway when you're not looking. He'll swear and spit at my mom or us, or hit us. He beats the little one up a lot. He has no friends at school because kids hate how strange he is, even though we've tried to teach him how to be a good friend. He's just so mean and cruel and heartless and incredibly annoying if nothing else. I sincerely hate him because he's always caused problems for my family, he goes out of his way to make our parents fight with each other. He even tripped my little sister when she was on crutches after having very painful foot surgery and when asked why he did it he said he thought it was funny. He told a little 8 year old girl in the third grade he wanted to have sex with her when he was 14. And had our little cousin do nasty things with him too, when he was 13 and she was about 8 or 9. He has a mobile therapist and a TSS and everything else, and it doesn't help. I think he just needs to go off someplace but my stepdad wont allow it. I hate the whole thing and can't wait for him to be out of that house even though I don't live there anymore.
