"These beings have been around since the dawn of the universe. They have an intrinsic understanding of what is right in the sense of what leads to greater organization, more freedom, and more of all of those things. They understand it in ways that we don’t.
So, the Green Lanterns are following a code of law that follows the fundamental principles of how the universe was created. We really want to go into that. I don’t think it’s been done before, to show that there’s more to this. There isn’t a bunch of law enforcers who are just out there traveling to say that it was wrong to cross that line, or wrong to be this person. They know the rightness in things. They know the wrongness in things, and they like to try and correct it for the evolution of the universe.
Yeah, it seems like a police force, but the more we get into the actual philosophy, the weirder and more alien it becomes."
