I think there are certainly crimes that deserve the death penalty (think CP type crimes). Just get those people out of society tbh, but this is just my opinion.
The only problem I have is with 100% certainly. You would have to be certain, or very very close to absolute certainty, that you have the right person who committed the crime.
If the person goes to prison for the rest of their lives, it will keep society safe from them either way. The death penalty is not making society safer.
People in maximum security prisons can, and do, escape. Sometimes the commit more violent crimes once they escape. A malicious governor can, in most states, pardon any person they want, and there’s no legal recourse. (In my state, the governor does not have the legal power to pardon a person until they’ve served at least 6 (?) years, and have been recommended by the parole board.)
On the other hand, people don’t get raised from the dead, no one gets resurrected, and there’s no reincarnation. Dead is dead, and is as safe to society as is possible.
The death penalty is certainly over-used, and applied in cases where it’s not likely necessary, but I absolutely, 100% believe that people like e.g., Gary Ridgeway should be executed as quickly as is possible.
The risk of me getting wrongfully convicted of something and getting a death sentence is higher than the chance of some dangerous murder escaping prison and hurting me.
Unfortunately being absolutely 100% certain is not a luxury we have in the majority of cases. People are framed, new evidence comes up, things like lie detectors and blood splatter analysis turn out to be junk science. Life in prison can get overturned and corrected if mistakes were made, death can’t.
Point about escaping/pardon. I acknowledge that society is ever so slightly safer when exceptionally dangerous criminals are executed.
About the risk of being pardoned by a malicious state, it’s true… But the other way could also be true that a malicious state can execute people who don’t deserve to be executed, like Snowden… Perhaps a compromise is to make particularly heinous crimes unpardonable? That would be a decent alternative to the death penalty, and it would be very difficult to repeal such a law.
As for escaping prison, it’s already rare that someone escapes from it. The solution is making better high security prisons for the most violent and dangerous criminals. I think it’s definitely possible to make escaping so difficult and dangerous that it wouldn’t be a problem. Make a prison on an island or an old oil rig, implants to track the prisoner’s location (a fancier version of the anti-theft tags in clothing stores), random X-rays to check they don’t have anything hidden in their bodies. All of these are definitely better than executing someone, though personally I think that maximum security prison breaks are already so rare it wouldn’t be worth it.
It is a deterrent. For instance, we wouldn’t have insurrectionists working in the highest levels of government if we actually had effective laws and enforcement.
It has been found that the greatest deterrent is “likelihood of getting caught”, and not the actual penalty. Think of the war on drugs. No matter how harsh they made the consequences, the drug trade continued. It’s like this: how likely are you to return a wallet you found to a lost and found if a cop was watching you, versus if you were out in the middle of the woods when you found the wallet?
It doesn’t matter if the penalty for not returning the wallet is death. If the likelihood of you getting caught is tiny enough, you will feel less terrified of playing those odds. Or at least, the average person will.
The death penalty isn’t a deterrent if you’re certain it will never apply to you.
