Should the death penalty be abolished?

Introduction

Capital punishment, also called the death penalty, is the execution of a person by the state as punishment for a crime, usually murder. It is one of the oldest punishments in law and one of the most fiercely debated.

Around the world, the long-term trend has been toward abolition. By the end of 2024, 113 countries had abolished the death penalty for all crimes, and 145 had abolished it in law or in practice.1 Yet recorded executions rose to at least 1,518 in 2024, the highest number since 2015, and Iran, Saudi Arabia and Iraq carried out more than 91% of them. These figures leave out China, which is believed to execute thousands of people every year but keeps its numbers secret.1

South Korea sits in between. The death penalty is still in its law, but no one has been executed since December 1997, when 23 people were put to death. In February 2010, the Constitutional Court ruled 5 to 4 that the death penalty does not violate the constitution's protection of human dignity.3 In the United States, 53% of adults supported the death penalty in 2024, the lowest level since the early 1970s.2

The debate usually comes down to three questions. Is it ever right for the state to take a life as punishment? Does the death penalty actually prevent crime? And can courts avoid executing innocent people?

Key terms

Capital punishment
Another name for the death penalty: execution ordered by a court as punishment for a crime.
Abolitionist in practice
A country that keeps the death penalty in law but has not executed anyone for at least ten years, like South Korea.
Retribution

Pros and cons at a glance

Pro: abolish it

    Con: keep it

      Pro arguments

      Con arguments

      Common clashes and rebuttals

      If Con says“Only execute when guilt is 100% certain.”
      Pro answersEvery exonerated person was once someone a court was “certain” about. Who sets the bar, and who checks them?
      If Con says“It's cheaper than keeping someone in prison for life.”
      Pro answersThe evidence points the other way: in Indiana, a death penalty case cost counties more than ten times as much.6
      If Pro says“It doesn't deter, so it's pointless.”
      Con answersThe research can't show it doesn't deter either.5 And deterrence is a bonus: justice for the worst crimes stands on its own.
      If Pro says“Most of the world has abolished it.”
      Con answersA trend isn't an argument. Each country should decide by its own values, as Korea's Constitutional Court did.3

      Around the world

      The US: 27 states still have the death penalty in law, while others have abolished it or paused executions.

      South Korea: abolitionist in practice. No executions since December 1997, and the Constitutional Court upheld the law 5 to 4 in 2010.3

      Debate tip: comparing countries is useful evidence on both sides. Pro can point to the global trend; Con can argue each country should decide by its own values.
