Because of the rules of engagement in the war against the human race in order to succeed in the competition not only must you be capable and willing to do harm you must desire it without realizing you do it.

 The human race has been greatly successful and the genocide continues in full Force.

I can hear you asking about those whom do realize they desire to do harm, those are your policemen your doctors your politicians the beings whom you depend on for survival.  The best examples of our society.

The weak go insane from committing these extortions. They are not fit for survival on this world of war.  The genocide, is the cleansing of the weak, for their unwillingness to be naturally cruel must be bred or murdered out.  If they can not be eaten, used as beast of burden or pleasure, they serve no purpose. 

We are a warrior race and only the strongest dominate.
