Death offers a quick escape from jail and the atrocities of the crimes these people have committed. Spending the rest of your life behind bars, with no hope of release, is a just punishment in my opinion. To whither away with no hope for the future sounds terrible.
My problem with this is prison life isn't a dark dungeon. They got a warm bed,food,medical attention when sick, entertainment, etc all on tax payer dime. Is it really that much of a punishment? I can see why some people think we should speed up the process. Its kind of sad prison life treats the prisoner better then he did the victim of the crime.
