How Do The Deeply Spritual And Deeply Religious Explain Evil People?

Are they Just soulless or possessed by something inside of them? How can someone let such evil and sickness take over them to commit such acts? It's also unfair that they are able to just get away with it and don't suffer any kind of consequences for their actions at all. In my honest opinion some crime are just unacceptable and unforgivable such as Rape, Bestiality, Racism Pedophilia, and Murder. What do you think? I want to hear everyone's prospectives.
