Have you ever read the book “One Child”, by Torey Hayden? It’s about a teacher and one six-year-old girl who had a police history a mile long, including attempted murder, and follows the teacher’s successful efforts to reverse the direction of her life.
Things happen for a reason. I’m sure there is more to the story than is being said here, just as there was a lot to be revealed in Hayden’s girl’s story. Individual, group, family, societal — stuff is likely messed up at every level, and this is more a symptom than a cause.
