There are numerous debates about the death penalty, as the opinions on this topic differ in different countries of the world. Most countries have abolished the death penalty, but there are still countries where it is used.
The effectiveness of the death penalty can be measured by the rates of crimes that demonstrate that this method of punishment does not reduce the number of criminal acts.
If the death penalty was an effective method for the prevention and decrease of crime, the statistics would demonstrate that states with the death penalty would have lower crime rates.
Conversely, the statistics show the opposite result, which means that it does not have high effectiveness.
Today, capital punishment most likely has other goals, such as revenge. It violates human rights, which is why a growing number of people are against this type of punishment.
