Utilitarianism is apart of the family of ethical theories. It was founded by Jeremy Bentham. The theory defines how moral actions are. Though it deals with morals, there are three main reasons why many views this theory has been problematic. One of those reasons is that it does not account for justice.
Sometimes, utilitarianism will violate the justice standards that have been put in place or ignore altogether. Another reason why it is seen as being problematic is that it does not have the ability to measure one's state of happiness or how well they are.
The last reason why utilitarianism is problematic is that it ignores obligations, such as to family.
