Of what good are dead warriors? … Warriors are those who desire battle 
more than peace. Those who seek battle despite peace. Those who thump 
their spears on the ground and talk of honor. Those who leap high the 
battle dance and dream of glory … The good of dead warriors, Mother, is 
that they are dead.
