In this theory, three beliefs arise: the moral law is known by human reason, applies to all and is constructed from human nature. In natural law theory, our actions should contribute to developing a person's life rather than what could harm them. In other words, our actions should not affect a person in a negative way. There is also a principle of double effect. This means that actions can be morally right even if the law says they are wrong and illegal. Regarding the dilemma, the broker should not conduct his business while on vacation because it would be wrong, according to natural law theory, for the broker to lie to the firm and use its funds to cover the cost of his vacation. The harm is that he defrauds the company by making it lose money for his own account.
