Utilitarianism Cheating

Utilitarianism is the idea that an action is morally right if the consequences of the action benefit everyone. In the case where a young man who cheated on his college entrance exam Utilitarianism says that this is not a morally right decision, because while the person who committed the action, the young man in this case, may benefit from the knowledge they gain from that education they got from that school, the action does not benefit the other young man or woman who did not cheat on the test and did not get into this college because the man who cheated took his place. The idea of Utilitarianism in this situation calls for the the young man retake the exam and use the new score instead of the score he got while cheating, because cheating only benefits one person not everybody.
Looking at this situation using an other ethical theory like relativism, where it is believed morals come from social norms. Society says that cheating is wrong, it is what most people have been taught from a young age, meaning that this goes against the social norm, which means that it is not a morally good act according to relativism. In this situation a relative thinker would say that that action of cheating is wrong and the person performing the act knows that it is wrong, therefore
If the young man insisted on using the cheated score, then doing good would be reporting him so that he is not able to use the dishonest scores. Doing no harm would be if the young man used the cheated scores but still didn’t get in, then people could just turn a blind eye to it, because it didn’t hurt anyone. The best standard to use in this situation to use would be to do the good thing because either way he cheated. The result of his cheating could mean that another person applying to the school might not get in because the school thinks that the young man who cheated did better, when really it was the other way
