How would the author most likely respond to the claim that the death penalty deters potential criminals from committing murder?

Also, the author never stipulates or speculates that the effectiveness of the death penalty as a form of justice is actually positive or negative. In addition, the author does not speak of any inhumanity or unfairness in regards to the death penalty.
