What is ethics? They are the moral theories that govern the behavior of groups or people and the rational analysis of morality. In fact, there are three fundamental values ​​in ethics which are life, happiness and the ability to achieve goals. People see the world selfishly and ethically. The selfish way is when the person only cares about their own core values. And the ethical way is when the person respects and cares for the core values ​​of others. It is also a moral point of view that involves classifying and recommending notions of right or wrong conduct. Mainly, the purpose of this article is to build the concept of ethical theories using specific examples or case scenarios. Kantianism, act utilitarianism, rule utilitarianism, the social contract and relativism are the ethical key. According to Thomas Hobbes, social contract theory means that there would be nothing of value if there were no rules or enforcement. Cooperation is the main idea that is understood in most cases by rational people. The government has resources and is able to enforce the laws. Moral rules are important when approaching relationships between communities or people, which is why acceptance of the social contract is necessary and accepted. Furthermore, according to Jean-Jacques Rousseau, there is nothing above rules or laws and this also prevents people from following immoral rules (Dave 2012). Social contract theory, in a more technical sense, social contract theory in the present has been adapted stylistically to examine overall expectations between science and community. For example; The organization of a well-known company is responsible for confirming the update of IT systems and the quality of the workspace. Company leaders must study the personal and professional improvement, physical safety and human dignity of all workers when analyzing a computer system which also follows social contract theory as it requires compliance with a set of moral rules such as confidentiality when modifying the computer system. On the other hand, if that person goes against the confidentiality policy for personal benefits, in this case he goes against the social contract theory. James Rachel's definition of social contract theory is when "morality consists of the set of rules governing how people should treat each other that rational people will agree to accept, for their mutual benefit, provided that others should follow those rules too."
