Lock this monster kid up and throw away the key. Before he kills a baby or toddler. He is definitely an A-one example of a “bad seed”.
We had a kid like this in our neighborhood when I was a child. Totally nuts. Good family, other children were normal. He tortured animals, set fires in the woods and finally tied his little sister to a bed and set it on fire. The parents got to her in time. I’m sure he ended up in prison at the very least.
