I'm fine with an occasional execution but the reason why they're rushing these don't seem to be right.
I support the death penalty. Any liberal laws lead to more crimes. Migrant crisis in Europe also proves it. Only the presence of weapons among the population is holding back a huge amount of crime in the United States. Here you have all the liberalism.
You're in EU? Do all countries there really have unarmed police? I really found that surprising and baffling at the same time. I live in a third world country and none of our police here would be caught dead without a gun. (Whether the gun actually work properly is a different issue.)
Death penalty is very difficult issue, from political side, medical, social, philosophical, religious etc.
In case of war, to defend the nation and people, soldiers can shoot and kill the enemy.
However, what if we are not at war?
Does society have a moral right to apply the principle of an eye for an eye, tooth for tooth, life for life, as in the Old Testament?
In the most countries in the world today, answer is simple no.
They do not want to destroy human life, but to rehabilitate the person and allow repentance and new life.
I think that such way is much more humanistic than death penalty practice today in America.
If someone is too dangerous for society, it is clear that we will not let him out.
I share your views on rehabilitation but there are some people who really wouldn't change, hard that maybe to accept. Or maybe we just haven't found the proper tools. Neurology seem to offer solutions in the future.
For now though, we are stuck with criminals where some may repeat the offense or commit worse crimes later. Provided they were really proven guilty, I'm fine having capital punishment as a final resort, as a last option for really violent offenders. That or keep them locked up and on medications forever.
