Nah, I'm going for; "The light is Meaningless without the Darkness. Good is Meaningless without Evil. Order is meaningless without Chaos. Haveing one creates the other by the very nature of it's exestience. All that we differ from you is that we realize this fundelemental truth. We are balanced. You,set the stage for atrocities in your ignorance."

Basicly, think True Neutral with a heathly dose of Fatilisim. They know there is no White, there is no black. There is merely grey.

So why would they wipe out that pesant village? Because they threaten the Goblin clans in the area. Among them, one day a leader will emerge. He will manage to unite most of the monsters in this area, and yes, he will drive the locals out. He will kill many. But. The nation he will found is pivitol in the goblin race. It will allow them to stop being raiders, to stop causing destruction. Their birth rate will fall, their nature will be tempered by civillization, and the Goblins will take their place as productive memebers of the world.

You know, that kind of thing

The greater good can often only be accomplished by the darkest deeds.
