Author's Purpose

From the text:

However, having survived, I needed to give some meaning to my survival. Was it to protect that meaning that I set to paper an experience in which nothing made any sense?

In retrospect I must confess that I do not know, or no longer know, what I wanted to achieve with my words. I only know that without this testimony, my life as a writer—or my life, period— would not have become what it is: that of a witness who believes he has a moral obligation to try to prevent the enemy from enjoying one last victory by allowing his crimes to be erased from human memory.
