The risk of executing innocent people exists in any justice system
There have been and always will be cases of executions of innocent people. No matter how developed a justice system is, it will always remain susceptible to human failure. Unlike prison sentences, the death penalty is irreversible and irreparable.
At the end of the day, humans are humans. They shouldn't be playing God. Capital punishment is a way that humans decide who gets to live and who dies. This shouldn't be in the hands of people. All humans should be allowed to live as long as God decides, even if we have to lock them up.
Anything other than capital punishment for the most heinous crimes is not justice in my opinion. There is no justice in the world more fair and right than "an eye for an eye, tooth for a tooth and a life for a life". Anybody who unjustly takes the life of another must pay the ultimate price. What kind of message will the justice system be sending out if they allow murderers to continue breathing, eating and sleeping in a warm cell whilst their victims lay decomposing in the cold hard ground? The death penalty may not be perfect, but as long as it deters most (not all) criminals aswell as providing closure to the families of the victims then no it should not be abolished at all.
We live in a world where heinous crimes take place everyday. The criminals who commit such crimes need to face justice or our society will fall apart. I don't understand why someone who willfully murders another person should be allowed to live. However, executions should only take place after someone has been proven guilty beyond a doubt.
Regarding the Ricky Gray execution, capital punishment should in no way, shape or form be abolished. Capital punishment represents the alternate and final justice. Exactly as these criminals have ended the lives of their victims, the criminals should meet the exact same fate. In fact, they should die the same way that they killed their victims.
