[retarded idiot] We should jail them for life instead. They can be rehabilitated! [/retarded idiot]
I don't think anyone out there is saying that rehabilitation should play a significant role in this case, since nobody is arguing that they should ever be freed. I think everyone understands this is either a life-without-parole or death penalty case.
This case is a good example of the difficulty in debating about the prudency of the death penalty. Assuming these guys are guilty (and I am highly confident they are), I have no real regard for their civil rights, because they are the worst kind of criminal scum and have left a wake of utter devastation as a result of their cruelty and selfishness. It is, accordingly, tempting to say they should be executed. There is no shortage of dreadful men on death row, most of whom are desperately unsympathetic figures based on their behavior.
The problem, at least for me, is that once we have a death penalty, it is available as a sentencing option even in cases where there is legitimate doubt whether a defendant is guilty or even whether a crime was committed (Cameron Willingham is a great example of the latter). I think our criminal justice process is probably the best ever devised, but it remains a human enterprise, fraught with opportunities for failed memories, personal grudges, and racial bias to enter into the equation. It's usually impossible to know for certain whether or not someone is guilty, and there are myriad examples of people on death row being convicted on weak evidence and later being proved innocent.
So, to return to this case, I am not a clergyman and I will not pretend to care about the fate of these awful men (Steven Hayes being by far the more awful of the two in my view - it would appear he is actually a fairly prolific serial killer). I will continue, regardless, to say that the death penalty is a deeply flawed, enormously expensive, and totally ineffective way of achieving justice, no matter how loathsome the person it's applied to.
