The Second Rule is that the greatest harm can result from the best intentions. It sounds a paradox, but kindness and good intentions can be an insidious path to destruction. Sometimes doing what seems right is wrong, and can cause harm. The only counter to it is knowledge, wisdom, forethought, and understanding the First Rule. Even then, that is not always enough.
Terry GoodkindReasons are the spoils of victory. When you've destroyed the enemy, then your leaders write down the reasons in books, and give moving speeches about them. If you've done your job, then there aren't any of the enemy left to dispute your leader's reasons. At least not until the next war.
