You might think you can replace Light and Dark with Good and Evil and call it a day. After all, the Dark Casters seem to cause most of the trouble, while the Light Casters are always fighting against it. But Beautiful Creatures makes it a little more complicated than that. For one thing, there's Macon. He's a Dark creature, a Lilum. Born to be evil, right? But he fights against his nature every day. Then there's Ridley, who doesn't seem 100% bad. And if she isn't all evil, who's to say that Sarafine, Larkin, or any other Dark Caster doesn't have a good streak, too? Are good and evil ever really that black and white?
