How does the death penalty protect society?

The death penalty can protect society by deterring potential criminals from committing serious crimes. Studies have shown that the death penalty can act as a deterrent to crime, as people are less likely to commit a crime if they know they could face the death penalty. Additionally, the death penalty can provide closure to victims and their families, as it can bring a sense of justice and retribution for the crime that was committed. Finally, the death penalty can help to protect society by removing dangerous criminals from the streets, thus reducing the risk of them committing further crimes.
