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: "Many things are worth dying for, but none worth killing for." 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: "There are perhaps many causes worth dying for, but to me, certainly, there are none worth killing for."
Prior to the attribution to Camus, the most widely publicized occurrence of such an expression was probably in the song "Too Long A Soldier" 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): "I've seen so much worth dying for, so little worth killing over."

Context: Among ourselves we differ in many qualities of body, head, and heart; we are unequally developed, mentally as well as physically. But each of us has the right to ask that he shall be protected from wrong-doing as he does his work and carries his burden through life. No man needs sympathy because he has to work, because he has a burden to carry. Far and away the best prize that life offers is the chance to work hard at work worth doing; and this is a prize open to every man, for there can be no better worth doing than that done to keep in health and comfort and with reasonable advantages those immediately dependent upon the husband, the father, or the son. There is no room in our healthy American life for the mere idler, for the man or the woman whose object it is throughout life to shirk the duties which life ought to bring. Life can mean nothing worth meaning, unless its prime aim is the doing of duty, the achievement of results worth achieving.
