Well, I could see that you are against it. :-)
But, I still have the principle of a life for a life, and I won’t budge on that one. I would imagine that quite a few others won’t budge either. I don’t think you’ll ever get support for that kind of a view to be implemented (i.e., kill someone if they aren’t rehabilitated after a specific period of time, whatever time you assign to it...).
you still don’t get it. Nobody hands down a death sentence AFTER someone serves time in jail. They get a death sentence at their trial or not at all.
