Obligation of Predators

You're driving along a country road, and you come upon a scene straight out of a horror movie - a pack of feral dogs mauling an elderly woman.  No other house is in sight, no other cars approaching, nobody else at all, just you in your car.  What do you do?
 
This is not fiction.  Some few face similar situations every day - cops who find themselves in a gun battle during a routine traffic stop, campers who awaken to marauding bears, or mail carriers who discover a house on fire.  In this particular case the young man on that road stopped and tried pull the dogs off the gravely injured woman.  The dogs would not be stopped.  They turned on and bit the young man, chased him back into his car.  He drove to a neighbor's house, who luckily had a gun.  Together they returned to the scene of the attack, but too late.  The woman was dead.
 
The young man did his best, under the circumstances - or did he?  He was certainly brave enough, and getting bitten himself demonstrated his perseverance.  What else could he have done?
 
We, homo sapiens, are the apex predator on Earth.  Quibble about strength, claws, and teeth, but there is no argument that disputes the obvious evidence of disappearing competing predators.  Not with claws or teeth do we rule the food chain.  Our strength is in our adaptability, and that adaptability is rooted in our use of tools.  Did the young man get out of his car as a brave man, or an apex predator? 
 
What is the difference?
 
Every car has at least half a dozen weapons inside.  A jack handle can shatter bone, crippling or killing with a single blow.  The heavy jack itself can deal a terrible blow.  Jumper cables would be a painfully effective whip, and unbreakable noose.  Windshield cleaner fluid contains ammonia and other chemicals that can cause pain to eyes, mouth, and lungs.  Emergency flares are obvious in their fiery threat.  Screwdriver, wrench, pliers, flammable lubricant, spray de-icer - so many things at hand to cause pain and carnage.

And therein lies the difference between brave hero and apex predator.  The young man's attempt to help the victim of the dog attack was laudable, but failed to demonstrate lethal intent.  Without the firm resolve to protect fellow humans and kill whatever hunts us, the young man abrogated his claim to predator-hood.

This is our curse and our obligation.  Darwin theorized that the most adaptable will survive and the rest drown in the flood of evolution.  Bravery is wonderfully human, but fails to live up to our obligation to self and species.  Bare your teeth and be ready to ruthlessly kill those that dare hunt Man.  That is our Darwinian obligation.

Roar.
