Law is a method to restrict human’s behaviour and it makes the society more safety. If someone breaks the law, they have to be punished. By the gravity of the situation, the punishments are different. Among them, Capital punishment, also referred to as the death penalty, is the execution of a person by the state as punishment for a crime. Regarding this punishment, people have fierce debates, some are against it; some are support it. Nowadays, only about 40 countries are still using the death penalty. From my point of view, death penalty is an effective punishment and it cannot be abolished.
if the death penalty did not exist, people are hard to notice how serious of killing someone; in other words, nothing could threaten their lives, because no matter what the criminals did, they do not have to die. Therefore, the crime rate could be increased. This mentality might make them imagine that “break the law just a piece of cake”, and they would do what they want to do without hesitation. However, death penalty bring fear to the criminals, a research shows that most of the criminals will express theirs penitence for the faults when they are going to be executed. In other words, they are afraid to die. In addition, the death penalty is also a tocsin for people, to warn them that never break the law. This is also a good way to decrease the crime rate. Especially for the large population counties, citizen's qualities are not at the same level. This is the reason that why death penalty cannot be abolished.
