I also agree that these people are evil. Not sick. not ill. Not misunderstood. Just evil.
However, I cant, in conscience , agree with the death penalty. No matter how much I hate scum who do stuff like this, the possibility of even one innocent person being wrongly executed is just too high.
My own solution would be that life in prison should be life. Natural life. No parole, no remittance. Furthermore, i believe that prisons should be more like they are in USA. They should be prisons, not home from homes. I am not talking about stalags or ” hell holes” but nevertheless, real prisons. 22 hours a day in a 12 fit by 12 foot concrete cage.
