Utilitarianism believes that the moral thing to do is to maximize pleasure over pain. This means that while some may suffer, as long as most prosper, it is worth it. Throwing few to the lions in the name of group entertainment is just. As long as the benefits exceed the downfalls. This is the principle which allows companies to determine which safety features to include in things like cars or household appliances. It can put a monetary value on life in order to way it against the profits a product can bring in. Or, it can deem a life too valuable to risk in any way shape or form. But ultimately, utilitarianism is the cost/benefit analysis of life.
