So which one is better – a serial killer or a terrorist? – Neither, of course. Furthermore, actions of a terrorist can even be justified – he fights for an idea or belief, thus trying to achieve some positive for own nation goal. As for executing terrorists, I don’t think they should be treated in any way worse than all the other criminals. If a terrorist has killed some people, punish him just like any other person that killed as many people would be punished. If nobody died, punish the terrorist just like any other person that has attempted to conduct a murder would be punished. Death penalty, in my opinion, is not a solution to the problem – terrorists will eagerly die for their ideas. Therefore, put them in jail and make work for the good of the nation they hate till the end of their days. This, I believe, will be the worst punishment for those who attempted to or killed the people of your country.
