Capital Punishment ANTI The existence of the death penalty in any society raises one underlying question: have we established our justice systems out of a desire for rehabilitation, or out of a desire for retribution? If a child grows up and murders someone for their wallet or just for fun, and they are in turn put to death, they are taught precisely nothing, because they are no longer alive to learn from it. We cannot rehabilitate a person by killing him or her. There is no credible evidence that the death penalty deters crime more effectively than long terms of imprisonment. The death penalty involves medical doctors, who are sworn to preserve life, in the act of killing Even the guilty have a right to life. There are alternatives to killing people.
