I do find it kind of interesting just from a sociological examination standpoint, however, how the United States is the only country in the First World in which the death penalty is still in use.
Japan and South Korea are hardly developing countries.
Japan and South Korea also have close to the lowest use of the death penalty among nations where it is legal. By contrast, the US executed more people in 2006 than any country except China, Iran, Pakistan, Iraq and Sudan. Even India, which has the death penalty and nearly quadruple the population, didn't execute as many people in 2006.
