Execution prevents the accused from committing further crimes.  POINT  The death penalty is the only way to ensure that criminals do not escape back into society or commit further crimes while in prison. While in prison, it is not uncommon for those receiving life in jail sentences to commit homicide, suicide, or other crimes while in jail, since there is no worse punishment they can receive1. Putting dangerous murderers in prison endangers other prisoners and the guards who must watch them. The other advantage of execution is that it prevents the possibly of an escape from prison. Even the highest security detention facilities can have escapees2. Thus, the only way to be absolutely certain that a convicted murder can no longer hurt others is to execute them. 1 Murdock, Deroy.
