Should Death Penalty Be Abolished?

Should death penalty be abolished or not has been a controversial topic around the world for several decades. In the United States, there are 35 out of 50 states which have death penalty, and according to the recent survey, 65 percent of the American population supports the death penalty as an appropriate punishment for murder. Supporter of death penalty believe that threat of the death penalty could be used to urge capital defendants to plead guilty, testify against accomplices, or disclose the location of the victim's body. People who against the capital punishment argue that the death penalty specifically and explicitly violates the right to life clause stated in most modern constitutions and human right treaties. However, I think the death penalty shouldn’t be abolished because its threaten power can reduce the criminal rate effectively.

In case to abolish death penalty, it needs to satisfy some qualification first, which includes a country has a very stable and secure society and low criminal rate. Yet America society is stable and secure, but its criminal rate is pretty high, we often hear crime behavior from news. Also, the prisons are crowded here.
Every time we mention death penalty, people will bethink of its serious consequences. In fact, severe punishment creates more fear. Therefore, the potential criminal or people who are likely to commit crime will threaten by the deterrence of death penalty, and the crime rate will decrease simultaneously. In addition, it sounds fear that if you take someone‘s life, the society decide take your own life to protect other innocent people, to eliminate the threaten from those criminal.

Although death penalty has its limitation of preventing crime, but I believe its threaten power does deter some crime, and helps reduce the criminal rate. Hence, the U.S should keep the death penalty.
