There is something inherently fascinating about the dark, about the more morally ambiguous parts of life, of others and of our own selves.
We want justice. People who believe in a just world suffer less stress and depression, and enjoy life more than people who do not. Many cultures teach their members from childhood to believe the world operates with natural order and justice – the just world phenomenon that comforts us because most of us, even the worst of us, consider our selves basically good and worthy. Our need to believe justice will prevail even when the system fails, even when criminals evade arrest or avoid conviction, makes us want there to be somebody out there who can and will get them eventually.
