In many countries, capital punishment is still a part of judicial system as their governments believe that it is a practical and useful preventive measure which should be used. In my personal opinion, it is a cruel and unfair penalty which should be eliminated from law in every corner of the world.
Capital punishment increases the level of cruelty within a society. When people are sentenced to death by the government, it gives the perseption that killing people is justified, if only it is for a good reason. This fact could create a society in which people might act violent in stressful situations and harm others, because in their subconscious harming others is not a big deal. For instance, in Saudi Arabia, criminals who are sentenced to death are executed in front of the public and everyone can watch someone’s life perishing easily.
Moreover, it isn’t just to take away one’s life according to what we believe has happened. A criminal is judged by the evidences which are gathered by police; evidences which could be misleading sometimes. We never can be certain enough in order to decide to end another person’s life, regardless of what he or she has done. In 1991, in the US, a man named John McArthour was charged with murder and at the end the verdict was capital punishment. The verdict was executed and 4 years after that the real killer turned himself in, and it was clear that John was innocent. This is a sad story showing us how wrong we can be in our judgment.
In conclusion, I believe capital punishment is not the right penalty, and not only it has a negative effect on society, but also it is not a fair sentence. We should eradicate it from law or we will end up having a more aggressive society, and more innocent people will lose their lives because of our misjudgment.
