With what Tartiflette said, I wonder if Dark Spire is Chaotic Evil. I mean, they just want to destroy anything that is not them, like Knight Templar, but I do not think they would turn on their own kind. If anything, the way they are presented, looks like they act on instinct. Dark Spire reminds me of ants, to be precise Army Ants. They move and destroy anything on their path, only recognizing and protecting their own. Everything else is food. If anything I think they are Lawful Evil, their actions not harming their own people.
I am guessing by Tartiflette's way of thinking, Lawful Chaotic Renegade?
