“A civilized man does NOT set out to harm another for absolutely no purpose. However, when he sets out to further his own purpose and fortune and in the process hurts someone else...well...sorry about that. It is called HUMAN NATURE.”
If that’s human nature, I’d rather not be human.
HUMAN NATURE translates to “competition”. When I try to make the sale, I am interested in furthering MY fortune by getting the commission from my rival. The football team striving for victory is doing it at the expense of the rival eleven. You translate this into ACTUAL PHYSICAL INJURY.
That is NOT the point of either the article OR what I wrote. MY self-interest may force me to “harm” the self interest of my rival——not his health or well being.
