Karana demonstrates how a code of conduct is important even when removed from human society. She decides never to kill another animal or bird. She notes that her people would find such a decision ridiculous, but she makes it nonetheless. "Animals and birds are like people," Karana explains, and as such she treats them like people. Over the years they have become her friends, and she wants to treat them like friends. Karana's characterization of the animals as people is the natural extension of her personification of animals from earlier chapters. Her conception of animals as people-like has been growing throughout the novel, and now she has brought it to a conclusion: animals are like people. Karana considers the animals to be not only her friends but also her family (since she refers to them as her children), thus it makes sense that they would deserve the same level of respect as people.
