There are some people that can not be a member to society without being violent....Even while in jail, they cause harm to others..... I think it should be used very sparingly and wisely and only on people that can not stop themselves from harming people no matter where they are or the amount of help they have received...that is the only time I think it should be used. But if the person is in jail, and is not causing harm to anyone around them, then just let them live their life in jail..... we shouldn’t murder people in general. I understand some cases, the crimes can be very harsh, but I think that person should suffer in jail for their crimes and never see an ounce of freedom ever again, than to be put to death.
