The nations of the world have engage in mass slaughter against each other because of pride. This pride is called national pride. National pride is the virus that infects the psyche of a nation and leads the people of that nation astray. War waged for the cause of national pride has taken the lives and destroyed the lives of millions in history. Tragically, history will repeat itself.
Pride is self-deceiving.
Every man has his dignity. I'm willing to forget mine, but at my own discretion and not when someone else tells me to. Pride makes our self-deceptions taste like candy. When we let pride run amok, we gorge ourselves on this delicious lie, and eventually we end up killing ourselves. On a global scale, we end up killing others because of pride's ability to blind us from the truth and from the true state of our humanity.
