Pagans in the movies and on television are sometimes depicted with questionable ethics, but these portrayals couldn't be farther from the truth. While Pagans lack a concept of sin, most do live their lives according to a code of ethics taught within their faith. And all Pagans recognize that they need to take personal responsibility for all their actions and the outcomes. Some Pagans have also adopted the concept of karma, the idea that each person's actions are part of a cause-and-effect system that will affect the future.
