Well I think it depends on who you are. Some people may think of death at that point as a release, while others may think that living to be imprisoned means hope to eventually become free.
What about the thought of a certain death sentence but a long unknown amount of time imprisoned until them - that would drive me insane.
I personally am not in favour of the death sentence in a modern, civilized system. The solution for people like this is difficult though. Who are you to offer someone another chance, someone who has had several chances and thrown them away with no remorse?
I can't help but feel by giving them another chance to commit while knowing the possibility is likely is almost enabling them to commit crime and hurt others.
Then again, what point is there in keeping some locked up forever with no chance of rehabilitation if your end goal is just retribution?
It is not hard to see why many are coming to the conclusion of the death sentence. I certainly don't have an answer for these specific criminals, though as far as general criminals go - i am always in favour of giving people the chance of rehabilitation and reform.
A work camp for people like this offers at least some production to come out of their imprisonment but work camps come with their own ethical issue.
Hang them all and the people that make excuses for them too.
Who is excusing them?
I can see people determining why they have ended up on this path but i dont see anyone excusing them, just condemnation.
