You could argue that the person commiting he crime is doing that [punishing those who love him] by their very actions which require said punishment.
And who the heck are you to decide that stealing vegetables "requires" the death penalty? I repeat, civilization will not last long if people believe that the proper punishment for theft is death. You're the one who said the punishment should fit the crime, and the only crime for which death can be a fitting punishment is to deliberately cause a death.
I have a hard time defending my libertarian politics because some of it breaks down into incoherence or silliness if you analyze it in too much detail. But one place where it does make sense is dealing with crime. If the major result of a crime can be measured in dollars, then it belongs in the civil courts and the proper judgment is restitution. If somebody steals your watermelons, they owe you the value of the produce plus a reasonable amount for your inconvenience, lost business, damaged fence, etc. If they do it again and again, or if they aren't productive enough to be able to raise the capital to pay you, well then you've got a person who demonstrates that he's not meeting the qualifications for citizenship in your community. He doesn't respect the rights of others and/or doesn't bother to carry his own weight.
At this point you've got a problem that is not one for the civil courts. Maybe you can deport him to a country that thinks that kind of behavior is just dandy. Maybe you can send him to remedial kindergarten and teach him how to get along, or maybe a therapist can find out why he's a jerk and motivate him to straighten out. I really hate the idea of putting people in jail, because it costs so much and because most of them come out worse than they went in.
But this discussion hasn't gotten to that point. Everybody's so excited about killing the melon thief that they haven't even postulated an alternative. What if you order him to pay for the melons? What if he can't or doesn't? What if he pays up and then steals more melons? These issues haven't arisen.
What people like about the death penalty is its ostensible simplicity. Snuff the perp. End of problem. It just doesn't work like that, is all. The perp has family and some of them are going to be really mad at you. Then when they kill you and your husband and children and dog, all of your other relatives and your children's boyfriends and girlfriends are going to be really mad at them, and the cycle of violence starts.
There was recently a murder trial in Virginia, a man was convicted of killing a woman. Her parents attended the sentencing hearing and argued for the death penalty. The convict's family were there too. One of them said, "Look lady, by older brother didn't have a valid reason for killing your daughter. But as far as I'm concerned, you don't have a valid reason for killing a member of our family either. He can stay in prison where he can't hurt anybody else, but at least we can still be a family. Why do you want me, a person who had no involvement in this crime at all and who had nothing to do with my brother growing up to be a murderer, to feel the way you do right now? What is that going to accomplish? Neighborhoods full of inconsolably sad people? If you want to kill him and make me spend the rest of my life crying, then you're no better than he is."
I'm glad I don't live in that neighborhood, because when vengeance killings start, the bullets go flying every which way and people with no involvement in the feud get killed.
Please don't try to turn the entire United States into one of those neighborhoods.
