Pi begins his journey as a peace-loving, pious, and vegetarian man. However, as he struggles to survive in the lifeboat, he feels himself changing. Time passes, and he slowly runs out of emergency rations. Even though he's a devout Muslim, in order to survive, he makes the decision to fish. He has no luck with catching a fish for a while, but he miraculously encounters a school of flying fish. He has an extremely difficult time coping with the idea of killing a living thing: "A lifetime of peaceful vegetarianism stood between [Pi] and the willful beheading of a fish" (183). Pi tries to make it as humane as possible by covering the fish's head with a blanket and everything. As he kills the fish for the first time in his life, he empathizes and agonizes over its death: "I wept heartily over this poor little deceased soul" (183). By killing this fish, Pi has become a killer. Pi says that he always includes this fish in his daily prayers.
Even though many people go fishing for leisure, Pi feels remorseful
for killing a tiny little fish for survival.
His downgrade to savagery has only begun with the first murder. Soon, he got used to killing and eating fish: "a person can get used to anything, even to killing" (185). Because the survival manual recommends that turtle blood is a great source of nutrition that also quenches one's thirst. At one point, hunger drives him to try eating Richard Parker's feces; Pi notices that he "descended to a level of savagery [he] never imagined possible" (197). Yet, he does not forsake his humanity. When the blind man he meets tries to kill him walks on Richard Parker's territory, Pi tries to save the man who tries to kill him.
Pi falls to this level of savagery due to his survival instincts.
