From the rampages of ISIS to the Charlie Hebdo and Boston Marathon massacres, from the strong religious overtones of the Russia-Ukraine war to attacks on American mosques and Muslims, and to the kidnap-murders of Jewish and Arab youth in Israel, the question regularly arises: Why do people kill — and die — for religion? But is this even the right question, when far more people who share the same religion, background and grievances of the killers refrain from killing? What other factors are involved?
