RE: Kill all criminals or deploy another method different from capital punishment.
From a systemic point of view, any death penalty executed is a violation in the system. Those who are convicted and punished leave those involved in a conflict. Both family members and the executive powers, such as judges, lawyers, administrative officials, doctors, etc., are involved.
Killings must be justified, administered, scheduled and carried out, but basically nobody can really do this in a responsible way. One only has to imagine what is going on in those who give a lethal injection, those who then take the body from the stretcher, transfer it, those who bury it or cremate it.
Everyone is witnessing a failure, which cannot be good for people's mental health. More prisons create more failed existences. More murders, more failed ones. Killing is symbolic of maintaining the justification of killing for those who in turn committed killing.
How can satisfaction take place when one life is given for another? How can the parents, brothers, sisters or children of a person sentenced to death not suffer pain? They belong to that person, even if they do not approve of what he did. Killing is the admission of failure of all in the system. It is the artificial bringing about of an end where failure is affirmed and set as irrevocable. How can one not be compassionate with those who are involved in the execution of death penalties? One must then insinuate that these people must make themselves insensitive to it, for how else can one cope with the conflict? How do people perceive a situation where they close the cell door and lock someone who is waiting for death? Certainly not as a success of human coexistence.
Do the relatives of the victims have satisfaction? Are they really satisfied when the perpetrator is executed? Do people really still believe that a just punishment has been carried out? We no longer live in such times and although the execution no longer takes place on the public pillory where the people watch, it is not very different. It only takes place in secret, in secluded rooms, and nobody who leaves there after everything has happened leaves with a good feeling.
Of course, on each point. An execution needs a executioner. Where does one find such a person? How does that person integrate into society after committing a state-sanctioned murder? How does one turn on the ability to kill, and then turn it off? The person who kills is irrevocably altered. And if they're not, then they are dangerous, because they lack empathy.
Of course of the issue of error hasn't been addressed. And the inequities with which the death penalty is adjudicated. Do the rich and poor have an equal chance of being sentence to death? How about race? Do people of all races stand the same chance of being sentenced to death?
