Because the people who would be killed, are people who cause suffering and misery on the world. Human life is sacred, so to damage it, or take it away is a sin that is beyond the pale. We only have once chance at life,,so for one of these monsters to come and destroy it, means that as far as I am concerned their lives have no worth anymore. Once you commit these sins, your life is no longer sacred, like the rest of humanity. The crimes they do is simply to much.

So, your response to me saying I don't understand why you would wish suffering on anyone is...because they caused suffering. Where is the logic in this response, I respectfully ask?
As for the real answer:
No. I would suggest strongly that we cannot go around picking and choosing who is worthy to live and who is worthy to die. We are all precious, and to suggest you have the right to decide who is worthy and who isn't is to set yourself apart from our race and claim some higher position. One thing you overlook is that people commit crimes- including violent crimes- for a number of reasons. The pressures and conditioning and experiences affecting each and every one of us cause us all to grow and develop and respond differently. To hold a person in a vacuum and say "their action means we must discard or reject them" is to take a shallow and flawed view of our societies.
You speak of monsters. Monsters are in the eye of the beholder. Look at it this way- consider a young man who goes out and stabs someone to death. Under your worldview, he is a monster and now forfits your care and empathy. Well, consider your nation's drafting of its young men during the Vietnam war, say. So, let's say this young man had his freedom taken from him, his people made it
quite clear his life meant nothing to them, that his job and duty was to put himself in harms way in place of more valuable people. Then lets say he comes back...and stabs someone to death, having learnt his own life means nothing, so why should anyone elses? He's probaby not consciously justifying it in these terms, but that's how he's likely come to see things. Your response? Apparently, to continue the attitude of dismissive non-empathy that helped create this problem. If we have monsters, then as a society I can only say "look in the mirror, Doctor Frankenstein". Treat a fellow being as disposable, convey an attitude lacking in empathy or care, and you encourage others to do the same.
Imprisoning criminals, for life in many cases, is necessary: to keep them off the streets and so keep others safe, to discipline them in order that they may learn control, and hopefully to rehabilitate them (though this is not always possible). But to abandon our duty to them as fellow beings, to abandon our care for them and respect for their status as sapient beings: this to me is unthinkable (and it's not often I use a word like that). To ignore general society's role in creating their criminal tendencies is equally unthinkable. My goal is to educate others, through example, never imposition, that my way is better. If you respond to hate with hate, it grows and becomes more powerful. Violence begets violence. Each life and being we turn from breaks down our civilization further.
Someone who truly cares about human life does not dismiss it- EVER- and certainly not on the justification that "oh, they didn't share my moral belief in the sacred nature of sapient life". Our people are what we make them. You cause suffering and misery- or at least contribute to and justify it- with your beliefs that criminals are sub-human and should be treated as such. Should I then say you should be killed for that? Where does it end?
I have never understood why anyone would hate or dismiss someone who has wronged them, or those they care about. Deep anger, rage, regret, sure. But hate? Dismissal? A ceasation of caring? If their crimes and lack of empathy affect you so profoundly, why do you wish to see such behaviour or attitudes repeated?
Sometimes, I think I will never, if I live to be 120, understand the way other people's minds work. To stop caring for another being is simply not something I can understand, let's just put it that way.
