What is utilitarianism and how is it different from natural laws and rights?

What will be an ideal response?

Natural laws and rights judge the morality of an action based on how well it adheres to broadly accepted rules, regardless of the action's actual consequences. "Right to a free press" is an example of natural laws and rights. A second framework, called utilitarianism, considers the consequences of an action, weighing its good effects against its harmful ones. "First, do no harm" is an example of utilitarianism, and as such, it is a precept of medical ethics ensuring physicians will heavily weigh the possible harmful consequences of each remedy. In many situations, both ethical approaches will lead people to the same conclusion about the proper action. But ethical dilemmas tend to arise when the application of different systems leads to different judgments about what is the ethical thing to do.
