In a word, don't let him do anything for others, just do what nature makes him do, and he will never make mistakes.I don't mean that he won't do nasty things and hurt himself, he may damage a lot, but it's not his fault either.Wrong behavior is due to the intention to destroy, and he has no such intention, but if he deliberately hurts, even once, his education is over, and it may be completely out of control.
