No one has the right to kill anyone

People don't have the right to kill any one. The Death sentence is not a right that can be imposed by people, who are not much except puny entities, who are limited in understanding. Not only that, but honestly speaking, people are strange creatures. All people have evil intent, except that the people who are good their entire life never show that evil, because for those people, evil doesn't become reality in time; evil isn't a matter of if, but when: many people die by the time evil can start to entrance them in life. But don't worry the entire time too much, because evil isn't a "thing", but rather a lack of something, that something being goodness.
