Difference Between Ethical Relativism And Act Utilitarianism

There are many different ethical theories that ethicists use to make decisions. If an alien civilization were to come to Earth and offer a cure for all human diseases, but would only do it if they were allowed to choose 10,000 involuntary human subjects for experiments that were most likely harmful, different theories would offer different explanations of why they think this situation is morally right or wrong. Two important theories that ethicists could use to help them make this decision are Ethical Relativism and Utilitarianism.
From a relativist perspective we are not allowed to judge other cultures for their actions because we cannot see their culture from their point of view so we have no right to have opinions on them. An ethical relativist
Act Utilitarianism states that the right choice is the one that will benefit the majority of the society and only takes into account that single act. I think that Act Utilitarianism would allow us to look at this situation and automatically decide that the best choice would be to allow this Alien to take those 10,000 people. There are an enormous amount of people around the world who suffer from the diseases listed, such as AIDs, many different types of cancers, and several other diseases. The majority of people would benefit from this exchange and just a small percent would be harmed. So from the Utilitarian perspective of wanting to maximize the amount of people who would benefit, the right choice would be allowing the Alien society to take those 10,000 people and perform these possibly lethal experiments. Although Rule Utilitarianism also wants to make the choice that will benefit the greatest amount of people, it differs from Act Utilitarianism in the fact that it also takes universal rules into consideration when making a decision. This definitely brings up a problem, because allowing these Aliens to take 10,000 people from earth against their own will and torturing them is against a universal rule. Without these humans consenting that these experiments can be done to them, their basic human rights are being taken away from them and it isn’t morally right for us to knowingly allow these terrible experiments to be performed on them. Allowing humans to be tortured and taking away their rights are against two major universal rules. Forbidding torture against one another and allowing everyone to have human rights are rules that have always benefited the majority of the people. If a Rule Utilitarian had to decide if this exchange would be ethical or not, they would choose not. Even though accepting this deal would benefit the majority of the population, the rules that were
