It's legitimately not if your actions were all the result of an accident. He feels he deserves to be punished but there's nothing they can do in the eyes of the law. What exactly do you want him to be charged with? It's a fire that likely started due to a fireplace door that may not have been fully closed.
btw they can tell when the actions are malicious. Some demons tried to kill a kid in this same manner after seeing this movie. They were caught.
