A child can not help but learn from the parents. The bad habits and not so good styles of the parents will be copied by the child. It's hard to throw them off! That takes low probability circumstances, or a fortunate, morally, adulthood where the child is blessed with the moral strength and external environment to do so. I think God gives all a chance to do so, so that's hopeful, but bad habits of the parent, like the good habits are by NATURE passed along, indeed, by NATURE, the more hurtful habits may be somewhat preferred.
