One of the most important rhetorical devices written in the novel is in the form of a metaphor: “He and Dick were ‘running a race without a finish line’” (202). At this point, the two have been on the run for quite some time; they are exhausted both mentally and physically. Although the murders were committed in cold blood, the act has made their lives horrible and unfavorable. Similar to the way a race can be tiring, the murderers’ are running from the law and dodging obstacles along the way.
Should their mental conditions have had an impact on their sentence? If you look at what they did, as well as their actions afterwards, I'd have to ask why anyone would believe their conviction unfair. Capote is against the death penalty.......... the rhetoric used, in addition to citing their mental conditions os Capote's speaking out against sentencing these two "sick" men, who've led terrible live to death. This is where parties divide on whether or not the death penalty should be abolished. Capote is quite good at stating his case......... but not quite good enough :-D
Perry and Dick’s criminal tendencies are revealed to have underlying medical causes (Perry suffers from paranoid schizophrenia, and Dick has brain damage from a concussion); the difficulty of the murder trial becomes, to what extent are they still accountable for their actions? In a larger sense, the book seems to grapple with the question of whether the same moral standards are applicable to all people, regardless of their upbringing and their life circumstances; or whether Perry and Dick are in some measure redeemed (at least morally, if not legally) by the fact of their mental illness, and the fact that their own lives have been so lacking.
