Why Questioning This Life

Why questioning this life? When I see some evil people Bombing innocent children in Palestine I remember about King Herod When he sent some military to terminate  innocent boys of two years old. I then ask , "Why quick death ?" Why their lives were too short on earth? Why questioning this life? When I walk around some African villages and meet some very old folks who are above hundred and thirty years and keep praying to die. I then ask ," Why life?" What did they do to live so long in the World? Why questioning this life? Many people always sing , " life is too short." some people are always praying to God to make them rest When they live so long.
