Why the mass shootings? Columbine, Virginia Tech, Las Vegas, and most recently the Waffle House, this is a short version of an extensive list that seems to keep growing.  Family physician, psychologist, and author Dr. Leonard Sax talks with me about a rarely discussed reason behind the violence, the spiritual. We unpack his First Things magazine article, "The Unspeakable Pleasure."

While mainstream media focuses on social causes like bullying, family dysfunction, gun control or even mental illness - Dr. Sax explores what the Bible always knew, and what we all knew until just a generation ago,  that we are not born good.  We are born inherently bad, and we must learn to control our violent impulses, especially, he says, young men.
