got violence?

In our current westernized society there is a common misconception that we, as a species, are NOT predisposed to violence against, well, anything. The past decade has fostered an entire industry based around our “inability” to process acts of violence (i.e. killing in combat).

Remarkable then, that the extinction of mega fauna coincided exactly with the propagation of humanity as it left sub Sahara Africa and spread across the Asian and European steppes. The complexity of man arguably only compounded as he realized how to fashion and manipulate basic and simple tools. The weaponizing of tools then generated an expanse of design, trial and error, and led us to the modern world.

At what point was that tool used to end another human life?

The very moment two groups met. By chance or by design. Two groups of early man met, they did not recognize one another, and conflict occurred. Fatalities may not have been immediate, but judging by modern habits, it escalated rapidly. The meeting was more than likely based on food and water procurement. Humanity is programmed to conduct savage acts of violence on one another. Period. Empires and great societies have been based entirely on there abilities to conduct large scale, intense combat. 

So after all this, if we were really not designed to kill, why would so many do it?

The sheep (non martial thinkers), need to realize they are suppressing their nature. The wolves (Martial thinkers), need to realize they are in tune with nature, accept it, embrace it and continue to train. And the bad guys need to remember the wolves are out there.......
