In the fourth part of In Cold Blood, Capote uses biblical references to make the reader understand the inevitable failure of the characters Dick and Perry. While Perry is kept in the women’s cell at the Finney County Courthouse, he recalls the time he spent with Dick before being separated. Since their imprisonment, Dick and Perry have not spoken. Capote writes of Perry’s remembering as, “Still, of everyone in all the world, this was the person [Dick] to whom he was closest at that moment, for they at least were of the same species, brothers in the breed of Cain” (259-260). Capote compares Dick and Perry to the biblical character Cain, who commits the first murder ever by killing his brother, Abel. Capote describes them as being “brothers in the breed of Cain” which refers to the other characters in literature such as Grendel who are given a disastrous fate because they are born in the murderous line of Cain. This gives an explanation for the dangerous and violent behavior and lifestyle the two murderers live. If it is out of their control that they are doing such horrible things, then the reader cannot help but feel that Dick and Perry are less responsible for their actions since they are destined to be evil.
