The United States is one of the last remaining developed countries to still use the death penalty and it is tine for it to be abolished. There is no evidence to show that it has any deterrent effect on crime and the costs to the state are tremendous. Eliminating the death penalty is the right and moral thing to do as the supposed leader of the free world.
I think capital punishment should end because I believe that there is too much room for convicting the wrong person. If someone is executed and is later found to be innocent, then it's too late to go back. I would rather see people sit in jail the rest of their lives than to execute the wrong person.
If you do some research, you will find serial killers, and rapists, and very sick and twisted criminals, in the State prison system. Some of these crimes are more heinous, or just as heinous as the crimes associated with the death row inmates. We see death row inmates being found innocent, after execution, and even innocent, and released, luckily, before being killed. Is it okay to have these kind of flaws, when it comes to a persons life, and death? Humans error, so, how can we put an flawed system in charge of the day a human dies?
