Widely attributed to Camus on the internet, the earliest attribution of such a statement to him yet located is an unsourced citation in Quotations from the Wayside (1999) by Brenda Wong: &quot;Many things are worth dying for, but none worth killing for.&quot; The earliest occurrence yet located of such a statement, by anyone, is one by Albert Dietrich in a 31 January 1943 letter to his conscientious objector status Hearing Officer, reported in Army GI, Pacifist CO : The World War II Letters of Frank and Albert Dietrich (2005) https://books.google.co.uk/books?id=3o4JN_C69VwC edited by Scott H. Bennett: &quot;There are perhaps many causes worth dying for, but to me, certainly, there are none worth killing for.&quot;<br>Prior to the attribution to Camus, the most widely publicized occurrence of such an expression was probably in the song &quot;Too Long A Soldier&quot; https://www.youtube.com/watch?v=YoQcU1ecPOc by Neil Giraldo and Myron Grombacher, sung by Pat Benatar on her album Wide Awake In Dreamland (1988): &quot;I&#x27;ve seen so much worth dying for, so little worth killing over.&quot; <br class="br">Misattributed
