Those who are at least honest about thier failings in the vulgar, brutal world are much easier to deal and reason with, than those who do not recognize fault in themelves every, but are quick to point out the failings of everyone around them.

Love thine Enemy. You have to know your enemy or you can never hope to defeat him. This is a collective Him of a bunch of people, not the singular him of the footman solidier. But regardless, to know the enemy well enough to defeat Him, you almost have to come to love him, to know his ways. Any thing else and you are constantly confounded by His Decisions.

The fastest way to make a collective enemy for your people, is too make sure the people never really meet except in battle when they are trying to kill each other. Because contact with the enemy sooner or later reveals 'He is Human", like you. And then you have a face for the enemy and it is hard to maintain the hate.

The only other fastest way to total and unrelenting Genocide, would be to perfectly translate any lanuage into your own, and find out what the bastards really thought of you. :Grin.
