My biggest concern with the death penalty is that mistakes are made. So many cases have occurred in the United States when somebody was sentenced to death and then it was discovered that the person wasn't guilty. Sometimes the person had already been killed and sometimes, luckily, they hadn't. I suppose the death penalty could be a reasonable punishment for certain crimes, if the system was always perfect. The thing is that the system can never be perfect, therefore I don't think it's wise to use the death penalty. I think it's best to lean towards a system like in Norway. There the inmates are treated kindly and they are given many opportunities to learn and become better, to prepare for their return to society. The maximum sentence there is 20 years.
