"Eyes of the Insane" is a 2006 single by the American thrash metal band Slayer, taken from their 2006 album Christ Illusion. The lyrics explore an American soldier's mental anguish following his return home from the second Gulf War, and are based on an article entitled "Casualty of War" in Texas Monthly magazine. "Eyes of the Insane" was written by vocalist Tom Araya during pre-production for the album. The song was generally well received by critics, and also peaked #15 on the Danish singles charts.
