Should the Death Penalty be used to Punish Violent Criminals

            Should the death penalty be used to punish violent criminals? Well, in my opinion I don't think it's right to take ones life. Even if that person is a crazy psycho maniac. They'd should be locked up in a mental institution or life in jail.
            I do not think it is right or justice to take ones life because of their actions or wrong doings. They are still human beings and God gave them a life to live, not for you to take away. If they commit suicide, then that is a whole different story. Even if that person is such a cruel, crazy, messed up, psycho maniac; he should still have a  chance to live. It would be best if they were just to stay in prison. If they are violent, like very very violent, then they should have those vest where they couldn't move their arms. And when they like get out of control, like they start to punch and stuff, then there should be a person with a tranquilizer gun to take them out. Then they would be punished furthermore. If that person is murders and murders and murders then that is the time to like keep him in a mental institute.
