Doctrine develops overtime. The modern world has advanced to such an extent that taking human life is no longer necessary.
Here is where I have problems.
I deplore the death penalty. It’s overused, executed poorly, and its true meaning has been lost.
In wealthy countries it is easier and easier to hold certain criminals safely. In developing nations it is not. Even in wealthy nations people seem to forget about inmate populations and the safety of guard, doctors, and other people who work closely with inmates. Guards are killed or injured often - it’s just never in the news. My closest and dearest friend is a prison guard. It seems every other week there’s news of a guard who has been injured, and he’s already known one who has been killed, but an inmate. Not to mention the inmates who are stabbed to death by other, dangerous criminals. The state knows darn well they can’t keep them safe without taking these dangerous men and keeping them in a dark box and fed through a hole in the wall. They are just too dangerous, and kept in a dark room and deprived of all human contact seems a fate worse than death, to me.
In my mind, and the mind of my friend, the death penalty is not a penalty at all. It’s not a deterrent, it’s not justice, it’s not revenge, it’s not tradition, or anything else. At the end of the day, it’s a terrible terrible choice that must be made when it is not possible to safely house, rehabilitate, and treat a dangerous criminal. There may come a day, someday, where we can. Maybe a kind of AR imprisonment system where offenders are linked in and unable to hurt anyone, but can interact with others. Who knows. But I do not think we have arrived at that day just yet, and I for one think ALL life deserves defense, especially those unarmed prisoners who are housed with smart, dangerous people who still manage to find ways of severely hurting or killing them and the guards protecting them.
And this doesn’t even touch on underdeveloped countries where any kind of inmate protection is impossible.
tl;dr: I believe the death penalty is still necessary, even in developed nations, but it is overused and the meaning of it has been lost. This step is too far, too soon, but I dearly hope one day it will not be.
