In this quote by Yasmina Khadra, the idea of being already "killed" is not meant to be taken literally, but symbolically. It suggests that the experiences, hardships, and struggles we have faced in the past have already "killed" a part of us, causing us to forget the pain and trauma we have endured. This quote highlights the resilience and strength of individuals who have survived difficult circumstances, showing that even though they may have been figuratively "killed," they continue to persevere and move forward.
