I would prefer it if we banned abortion and euthanasia without destroying valuable military capabilities.
The death penalty, furthermore, is a necessary deterrent against mass murder, although I do favor limiting its application to murderers whose guilt is not disputed, including all prior murder convicts (we owe it to the inmates in the prison to reduce the risk of being maimed or murdered by another inmate, and as I see it the best way to do this is to reimagine life imprisonment as what one might call “vital probation”, with prisoners sentenced thus subject to termination if they were to kill another prisoner or attack another prisoner with homicidal intent using a bladed weapon.
What Field Marshal Sir Bernard Law Montgomery said regarding the Nuremberg trials is equally applicable to American justice with regards to that most frightening category of criminals, that of the murderers, killers, cutthroats and thugs, bloodthirsty and psychopathic, and that is, that even for such monsters, we must present justice that is firm but fair. Firm in that those who can be proven to carry guilt should be swiftly cut down by the sword of Justice, fair in that those where even some doubts exist, less than reasonable doubt, but the unlikeliest possibility of innocence, should be spared, but put on notice that should they harm a fellow prisoner, their probationary existence shall be brought to a swift and unsympathetic close.
I should also note in closing that there appears to exist in Scripture a positive commandment to execute murderers, and that such executions were viewed favorably by both Patristic authorities of the common Catholic and Orthodox heritage, as well as the Scholastic theologians unique to Roman Catholicism.
