They are immoral when the general values are violated. The material object, on which an action rests, can be of good or bad character from the moral. An object can be good or bad in the reason of the rules, the situation that is presented, or the intention or actions. In another sense, an object of a morally good nature can, in some circumstance, become, in a work of the situation, an immoral object.
