"Thou shalt not kill". I don't think state killing of prisoners or, indeed, any human beings can be justified
"Thou shall not kill" is a poor English translation. Should be "Thou shall not murder". Big difference here. There are plenty of examples of the dealth penalty used in the Old Testament, tho' I find many to be inappropiate for the crime mentioned.
True, Jesus talked about loving one's enemies in the New Testament, but I think he meant that on a personal level, not as an excuse for government to go soft on serious crime. It bothers me when there is more concern for the criminal than the victim.
I understand that people who do horrific crimes often, though not all, have rough childhoods. This does not excuse their behavior as an adult and to let them off with a television set in a jail cell for the rest of their lives does not add up to justice and accountability. And there is a difference between justice and vengance.
Some get religion & have a heart change, but not enough to justify going soft on these crimes. I would, however, do away with the dealth penalty on convictions where there was only circumstancial evidence, so that we don't risk excecuting an innocent person. DNA evidence has later found some on death row to be innocent.
At the same time, I agree with Wanda in that people are in prison way too long for minor crimes. I'm not a drug user but still think we got way too many pot smokers going to jail. They are not hurting anybody, so I say leave them alone. I think the war on drugs is sham anyway, an excuse for the government to have more control & further invade our privacy with searches etc.
