OPINION: Should we call ISIS 'evil'?

When most people look at ISIS, they see the incarnation of evil. Among its many horrific acts, the Islamic militant group beheaded American journalist James Foley and posted the video this week in retaliation for U.S. airstrikes in Iraq. The Pope typically protests violence, but he implied that he supports the use of military force to combat ISIS. Even al Qaeda says ISIS is too violent. Across the political spectrum, public officials and pundits have characterized them as "savages," a "cancer" and the "face of evil."
