How about you? You're positive to death penalty ? If yes - can you argue from a christian ethics perspective ?
Everyone in the entire world has benefited from the death penalty
In 1892 fingerprints were first used to solve a crime. The officials had a witness who saw the crime and identified the murderer and they had spent days trying to beat a confession out of him but he refused to confess. Generally speaking in those days that would not stop them from throwing you in jail, however, because in this case the man would be put to death for the crime (it was a death penalty case) the investigator wanted to be sure. That was when they first used fingerprints to prove who the killer was and as it turned out, this man was innocent, the woman who claimed she saw him kill the children was in fact the killer. It is hard to calculate how many years of innocent people being put into prison have been eliminated because of that one discovery, and it never would have happened had it not been for the death penalty.
You see, what happens is that people really, really do not want to be wrong about giving people the death penalty. It seems they aren't so squeamish about sending innocent people to prison, back in 1892 estimates suggest that as many as 1/3 of all prisoners were innocent.
When I taught Forensics we went over many of the discoveries that were made and it hit me that the vast majority of these discoveries were made during death penalty cases and the reason they were made was because it was a death penalty case. Often the investigators were able to convince scientists to drop everything to help them simply because a man's life was on the line.
Now as far as I am concerned putting an innocent man in prison is a horrible crime too. You rob him of years of his life and you slander him with a false conviction that will be with him for his whole life.
So then, anyone who is against putting innocent people in prison for crimes they did not commit supports the death penalty, whether or not they understand that. Because the numbers of innocent in prison is way down from 1892. A reasonable estimate is 2-6%. But that is very misleading because if you have money in the US and can afford the best lawyers it is virtually impossible to be convicted unless you are guilty.
Which brings me to why I support the death penalty. About the only reason that innocent people go to prison these days is because they can't afford the best legal defense. However, that does not apply to people on death row because there are incredible resources available to them for free and you are given enough appeals that it generally takes 25 years before the sentence is carried out.
What I don't support is prison. In the Bible there is no prison. You get sold as a slave. For example, if you stole 100k an employer might come in and say they'll pay that 100k if you work for them as a slave for five years. So thieves do not go to prison. Rapists, it depends, if it was date rape either the rapist marries the woman he raped, or he pays the father a heavy price if he refuses him to be a son in law. However, if he is deemed a predator attacking and raping women who fought back then he is put to death. You don't put people to death for assault, back then it was "an eye for an eye" but you paid a very heavy price for injuring someone. Again, if you can't pay that price you are sold as a slave for the number of years it will take to pay off that price. Finally, murderers are put to death. A murderer is not a person being attacked with a deadly weapon who defends themself, that is called self defense.
What has happened in the US is the prison system has become big business. A criminal justice system is supposed to reduce crime and make the society safer. That is not what our prison system is doing. It is robbing men, as a result you have many children in broken families, you have gang members and poverty. Meanwhile taxpayers are the ones who pay the price for these crimes, not the criminals.
From 2020 to 2023, a four year period we averaged less than 20 executions nationwide. Meanwhile we average around 20,000 homicides nationwide each year. So 99.9% of convicted killers do not get the death penalty. Generally it is only the most horrific crimes where multiple people are killed and children are killed that would get the death penalty. Serial killers, terrorists, these are the people who get the death penalty.
Probably the most common use of the death penalty is using it as a bargaining chip for a murderer to confess. They offer the criminal a deal that if he pleads guilty he will get life and they'll take the death penalty off the table.
So this deals with the primary objection to the death penalty which is that innocent people are killed. The other objection to it is that the death penalty is more expensive. It is cheaper to the taxpayer to give a person life in prison than the death penalty because of all the appeals they get. I completely disagree with this objection, I want the death penalty to be the most expensive option. Why would I want it to be cheaper to kill a person? I don't want the judge to have any reason other than the fact that the person was guilty beyond a reasonable doubt of a truly horrific crime.
