I have to disagree with you. Capital punishment is the true, the only real justice for murders victims. Murderers for killings must get death penalty. You can read my new post about how in United Arab Emirates in contrast to the western world, especially in Europe and my native Lithuania justice really triumphs. Read about the case described in the post and let's see if you would feel sorry for the terrorist's life and want to keep her alive and mock the motherless children of the victim.
