So two wrongs make a right
Quit trying to trap people into dichotomies so you can drop this stuffty line. There is a real world application for the death penalty and this cheeseball line from a 1730's poem has no bearing on anything. If a man breaks into your home and starts trying to stab your daughter and you shoot him in the head, is that an example of "two wrongs"? If you capture a maniac who shows a clear disregard for social norms and human life and the potential to commit murder upon release, is purging the forget an example of "two wrongs"?
Locking someone in a cage is 'wrong'. Killing someone is 'wrong'. The entire judicial system seems kinda twisted when you look at it from the incorrect context, but it's a very real and absolutely required system that's been in place for a very long loving time. Criminals know the difference between right and wrong when they commit crimes, and sometimes the crime is so heinous and the perpetrator is so callous that we can appropriately deem it's better off for humanity to just simply purge the perpetrator.
I'd say that the punishment fits the crime, but I know you'll just drop Ghandi's proverb about the whole world being blind or some gay hakuna matata bullstuff, but here's the thing: The dealth penalty is far from an easy sentence to get. Not only do you have to commit a crime very, very dastardly to even have it on the table, but you also have to lie about it and try and get away with it. Normally if you confess, tell the prosecutors where the bodies/evidence is, and co-operate with the law, it's taken off the table/the sentence is reduced. There is an on-going debate throughout all of America of whether or not the death penalty is a right or wrong in the context of the victim vs the perpetrator, and that's why this topic exists. It's not an argument about "is it ok to do a bad llolololo" because there is still debate whether or not capital punishment is actually socially wrong. We determine the need for capital punishment through objective ideas, like whether or not the government has too much power, whether or not it's actually beneficial to society to kill heinous criminals, whether or not the punishment fits the crime. Not subjective ideas, like what some wet-wipe teenager with no real worldly context believes is "immoral"
