Diaspora

Beah takes a very emotional journey throughout the war. He goes through a lot of mental and physical anguish. When he first starts out on the journey with his new traveling companions, he is scared. But as the their travels progress, Beah and his companions slowly start to diminish as the children that they once were. Beah's friend Saidu descries it best when he says, "Every time people come at us with the intention of killing us, I close my eyes and wait for death. Even though I am still alive, I feel like each time I accept death, party of me dies. Very soon I will completely die and all that will be left is my empty body walking with you. It will be quieter than I am." (Ch. 10, pg. 70) And by the time they are recruited into the army, and start killing rebels, they have officially lost their childhood innocence. Beah and his friends also go through physical changes as well. They start as starving, tired, and hurt children. And turn into well fed, drug addicted killing machines.
Beah looses the culture of humanity while going through the war. Once he becomes part of the army, he does not care about human life or worth anymore. He is happy to kill the people that killed his family. He no longer sees the rebels as people, as men and children, he sees them as murder's. The image of blood and gore no longer becomes terrifying for Beah or his friends, it becomes a source of power, as well as a reparation for what happened to them. They loose the grasp of human worth, and the culture of humanity.
Being in isolation was the biggest factor in causing Beah to loose his grip on humanity. Once he becomes separated from his brother, Beah goes into complete isolation. Even when he is with the new companions he is still trapped in his own isolation. Beah talks about how him and his companions never really talk about each other. Beah keeps himself within his head, which is the center of his isolation. The death of his family, and a few of his friends pushes him deeper into isolation. He does not get the opportunity to properly grieve, which only works against him in his slow diminish into a killer.
