Extremely violent crimes creates a huge damage for society. Violent crimes itself creates fear, trauma, and vulnerable condition for any human being around it, especially the direct victims. Extremely violent crimes can vary from terrorism to genocides. All extremely violent crimes are forbidden by the United Nations through some treaty and regulations. Therefore, a harsh punishment is needed to make sure the perpetrators pay for their deed. However, in the name of human rights, other people might think it wasn't right to kill criminals. It is believe that violent crimes subjects were human before they were criminals. But in my opinion, it is better to put a death sentence to perpetrators of extreme violent crimes. They deserved an equal punishment to the damage they have been done to the society.
