There is no one moral philosophy that adequately covers every situation. If there was we'd just use that and not have all of these other options. They are tools to consider (and sometimes reject) just like other parts of philosophy. What Utilitarianism is good for is making policy decisions that are not directly related to human rights, and therefore may not have a clear cut answer in other philosophies. [edit clarity]
