In my opinion, it is in part to appease the public, yes. These men murdered for money, they are below everything as human beings, and their actions put their families in danger. Many believe death is too sweet for the like of them. Many believe it is only justice that they suffer. Comparing them to animals is an insult to animals. Maybe I'm not evolved enough, but I don't feel sorry for them. On the other side, I do see your point, torture is an evil thing.Yes, yes, I know who we're dealing with. As I've already said, I'm in favor of the death penalty in certain cases, but I'm against torture. Any emotion in what I said? Yes, of course. I'm a human being, not a piece of plastic. And I saw myself inside this box that these assassins will live till the end of their lives. But the question is this: why did they decide on this penalty? Why not the death penalty? Was it to appease the public? Is it a message to others, to those who are planning other attacks? Is it to accept torture as a means of justice?
Of course I also understand the situation, the tragedy that has happened. So I see this judicial decision as revenge. And I wonder if revenge is a good thing.
And I agree with you, living in a box for the rest of your life is cruel. The little sanity they have left will evaporate in a matter of weeks. However, I also think mercy is wasted on psychopaths. These men have proven that they are unsalvageable, and any mercy would give them leeway to harm people again.
Russian authorities probably took these elements into consideration. I'm not sure revenge plays a big part. They wanted to appease people's bloodlust, so they would not be any justification to retaliate against the families of the murderers, Tajiks or muslims. They have to protect and keep a muticultural, multi-ethnic country together, and to do that, they need to display what happens if you dare endanger that unity.
Another element is that Russia is at war and has to appear strong and ready to use violence to protect its citizenry.
In the end, even if these guys are MK ULTRA victims, they have to be severely punished to ensure that the country stay united, that the Russian people feel justice is served and no resentment, no mistrust will fester.
