Killer Instinct

A warrior must be vicious, capable of extreme violence. Some consider this revolting, at least until they need a vicious person to protect them. A warrior must be more vicious than his adversary. Modern soldiers are supposed to be guided by the Geneva Convention (the rules of war); as if you can impose rules on the enemy. As exhibited by the 9/11/2001 attack on the United States, the enemy has no respect for the Geneva Convention. To convince the enemy to stop its aggression, you must be more ruthless than they are, or you will fail. If you do not believe it, just look at the results of wars, both ancient and recent.

A warrior has a unified mind that is free from distractions and fully focused on the enemy. Distractions are derived from two sources: internal, where the mind wanders or panics; and external, such as an adversary attempting to "psych you out" or environmental conditions such as weather, lighting, terrain, etc. acting upon your senses. A warrior must control thinking, situational awareness, adrenaline manipulation, physical mobilization, psychomotor control, tunnel vision, courage, tactical implementation, breath control, pain tolerance, and habituation to violence.

Everyone has a killer instinct. In some, it is weak; in some, it is strong. In some it is suppressed, in some it is expressed. For the warrior, the killer instinct must be nurtured and cultivated into a controlled response that acts for the good of all.
