I have an 8 year old son who shows no emotions other than happy no matter what is happening. He has sexually abused my younger children, self harms, lies constantly, intentionally starts fights between his father and I who are divorced,(he finds extreme joy in that one) and no matter how much trouble he is in, he always has a smile. He never feels like hurting himself or others is wrong. He thinks its as natural as breathing. Should I get him out of my home?
