I am, and have always been, against the death penalty. I accept that means sometimes there will be people who have committed such a heinous crime that you cannot bear thinking about the horrific details, alongside some sad cases of inadequate people who may stand a chance of being rehabilitated.
We have to accept that if there is no death penalty, it's the same for all murderers.
There is capital punishment in some states of America and it is no deterrent, murders still happen all the time.
We have to keep on trying to make society better, even a little progress is worthwhile. We have come a long way and still have a way to go, no doubt always will, human nature being what it is.
