Should the death penalty be banned in the United States?

Should capital punishment be banned in the United States? For those who are not aware, capital punishment is another word for the death penalty. The death penalty is a punishment that can be administered to someone convicted of committing a capital crime, in which they are executed. While the death penalty has become rare in recent years, with some states even banning it, it is still federally acceptable to sentence someone to death for committing a capital offense. Some believe that it should be banned federally because it is barbaric, and violates people’s basic human rights. Others feel that it brings closure to the families of victims, and that justice is properly served when people are executed for committing these heinous acts. What I would like to know more about is how much money it costs a taxpayer for someone to be executed, and for someone to spend life in prison. I would also like to know more about what all of the capital offenses are, and why death penalty sentences are becoming less frequent. I think it might be difficult to add to the conversation down the line, since this has been something that has been debated for quite some time, but I think after doing more research I can find a way.
