It depends on someone's connection to God.  If someone does not believe in God, than it is likely that someone will not connect to the words.  However, the ending can be universal in the hope of peace.  Even connecting and believing in God, it can be difficult to have to praise God, when a loved one has just died. Alternatively, many people can find comfort in the idea of the Messiah and the fact that their loved ones will be brought back to life.

Leonard Cohen proclaims the opposite! In "I want this darker" his language is half ironic and half honest. He speaks to God, claiming he is "ready" for the darkness, to be crucified, vilified, yet arguing that if god is the "healer," it means he's "broken and lame." He is caught between accepting the fate that God has given him and resisting it psychologically. Kadish doesn't "fit this state of mind of mourning," rather it shapes it. By saying Kadish, one adopts the frame of mind that one is "ready" despite the initial ambivalence.
