<human>: What is an argument for and against the death penalty?
<bot>: Argument For: The death penalty is a strong deterrent to crime, as it serves as a warning to potential criminals.2 Arguments Against: It can be expensive to execute people, especially in countries with limited resources.3 In addition, some people believe that executing someone does not actually serve justice, since the person who committed the crime may have already served their sentence.4 Finally, many argue that there are more effective ways of punishing criminals than execution, such as life imprisonment or other forms of punishment.
