"Do not want to do anything to others" is regarded as a virtue by many people, but it can also lead to contradictions. For example, no one wants to marry a doctor who works on a weekend and calls at two o'clock at night, but every patient Hope to find such a doctor. From this we can infer:. ['the more ethical a doctor is, the harder it is to get married.', '"doing nothing to others" is the real virtue.', '"don\'t do anything to others" will only cause pain.', "what one doesn't need is sometimes exactly what another needs."]
