Massachusetts (and the other states without it) really ought to bring back the death penalty at the statewide level, too.
To what end?
To the end of not supporting murderers (and, while this wouldn't happen, in an ideal world perpetrators of other sufficiently severe crimes, such as child or serial rapists, who will never be rehabilitated) until the end of their livesTo the extent that one of the State's core interests is in the continued bodily existence of its citizens, I'm of the opinion that this should be applied in as comprehensive a manner as possible, even if nothing else is.
The Commonwealth of Massachusetts has a definition of justice that generally inclines at least slightly more towards the restorative than does that seen in Westerns and samurai films, and I'd like to see it kept that way.
