By now, we hope you understood why the death penalty does not violate the 8th Amendment. As we do agree with your argument, we strongly believe that the death penalty gives justice to the victims and is essential for a safe society in today’s world. Without these sinful criminals in our community, the world can be a better place without them and their influence. The death penalty gets rid of these people and is essential for a fair and secure society.

All guilty people deserve to be punished, only guilty people deserve to be punished, guilty people deserve to be punished in proportion to the severity of their crime

This argument states that real justice requires people to suffer for their wrongdoing, and to suffer in a way appropriate for the crime. Each criminal should get what their crime deserves and in the case of a murderer what their crime deserves is death.

It is undeniable that those who are executed cannot commit further crimes.

It is often argued that the death penalty provides closure for victims' families.

Incentive to help police

The argument goes that the death penalty reinforces the belief that bad things happen to those who deserve it. This reinforces the contrary belief; that good things will happen to those who are 'good'.

There is no better way to help the families other than death. The death penalty makes sure that the criminal does not make the same mistake again and makes sure that the influence of the criminals doesn't move on towards other people.

Our 7th point is that the death penalty can make sure no one else can make the same mistake again. If the criminal knows that the justice system will not stop at putting him to death, then the system appears more draconian to him. Hence, he is less inclined to break and enter. He may have no intention of killing anyone in the process of robbing them, but is much more apprehensive about the possibility if he knows he will be executed. Thus, there is a better chance that he will not break and enter in the first place.

Our fourth point is that it's far more likely that the criminal is guilty. Errors will occur in any justice system, but the through due process of executions, above the process of any other punitive measure, may make the margin for error in capital punishment cases that much smaller. It’s far more likely that those facing death are actually guilty of their crime as a result.

There are many victims of a single murder. The criminal gets caught, tried, and convicted, and it is understood that the punishment will be severe. But the person he has killed no longer has a part to play in this. Unfortunately, the murderer has deprived his family and friends of a loved one. Their grief begins with the murder. It may not end with the murderer’s execution, but the execution does engender a feeling of relief at no longer having to think about the ordeal—a feeling which often fails to arise while the murderer still lives on. A system in place for the purpose of granting justice cannot do so for the surviving victims, unless the murderer himself is put to death.

Our second point is the justice for the victim and his/her family. The death penalty is an important way for a safe and fair society. If a victim has died, then the only way for a fair society is to kill the criminal. It is not fair for the victim if the criminal is still alive and is able to make up for his fatal mistake. If a criminal is released from prison, then why can't he make the same mistake again under alcohol or drug influence? The death penalty makes sure of the victim's justice and that the criminal can't make the same mistake again.
