If a man kills another person, it is a bit rich that he objects to society exacting justice. Scared of death? Grow a pair, I'd say. Easy to pull that trigger--not so easy to be on the other side, eh?
If people object so much to the death penalty, one option I would support is that these folks personally pay 100% of the cost of incarcerating the killer for life, as well as the cost of reparations to all victims' families, the exact amount to be determined by the victims at their own discretion. If the victims want millions, then that's what the death penalty opponent should pay. Billions or trillions would most likely exclude any possibility for parole, although perhaps collections could be taken among all the death penalty opponents in the world. I'd like to see the first victim-trillionaire.
I also believe those opposed to abortion should pay 100% of the cost of raising those fetuses that would otherwise be aborted. They can pay for college, as well, at a four-year institution of the parents' choice. That would probably run to about a million dollars. I say cough up the money, if abortion is so bad. Get a second job moonlighting at McDonald's.
What we don't have in the world at this time is any shortage of human beings. The number being generated far outnumbers the number lost through the death penalty or through abortion, and it could be argued, the quality gained is better than that lost. If a mother seriously wants to off her offspring, if that is her final choice, then she probably was not about to give birth to a rocket scientist, a saint or a great leader. Daddy must not have been all that great, is the most likely conclusion. Never a good scenario for a kid to grow up unwanted. And there are killers a-plenty in the world, and offing a few here and there through the death penalty is not going to keep this world from turning. If a killer's death brings a small measure of solace to the victims, or relief that they won't have to attend any parole hearings, so much the better.
