Well-intentioned people sometimes attempt to resolve the marital problems of their friends. But these attempts are usually ineffectual and thereby foster resentment among all parties. Thus, even well-intentioned attempts to resolve the marital problems of friends are usually unjustified. Which one of the following principles, if valid, most strongly supports the reasoning above? ['The intentions of an action are irrelevant to whether or not that action is justified.', "One should get involved in other people's problems only with the intention of producing the best overall consequences.", 'No actions based on good intentions are justified unless they also result in success.', 'Interpersonal relations should be conducted in accordance with doing whatever is right, regardless of the consequences.']
