A more thorough explanation:

Utilitarian-deterrence theory is a legal theory that suggests a person should only be punished if it benefits society by preventing future harmful behavior. This theory is based on the idea of hedonistic utilitarianism, which focuses on maximizing pleasure and minimizing pain for the greatest number of people.

For example, if a person is caught driving under the influence of alcohol, they may be punished with fines, community service, or even jail time. The utilitarian-deterrence theory would argue that this punishment is necessary to deter the person from driving under the influence again and to prevent others from doing the same. By punishing the offender, society benefits from a decrease in the number of drunk drivers on the road, which ultimately leads to fewer accidents and injuries.

Another example could be the punishment of white-collar crimes, such as embezzlement or fraud. The utilitarian-deterrence theory would argue that punishing these crimes is necessary to deter others from committing similar crimes in the future. By punishing the offender, society benefits from a decrease in financial crimes, which ultimately leads to a more stable and trustworthy economy.

Overall, the utilitarian-deterrence theory suggests that punishment should be used as a means to prevent future harm and benefit society as a whole.
