I'm against the death penalty but for an unusual reason that not many have/agree with.
I think it's too good for the very type of criminal it's generally reserved for! It's an easy out for them. I'd far rather they be locked up for life, with no luxuries. Let them have to live with what they've done and the consequences for them even if they don't feel guilty. In addition study them so we can try and reduce the creation of such criminals (not always possible I know as with certain types there are genetic and brain physiology factors) and also so we can more easily spot those likely to commit such crimes and manage them appropriately.
I also feel it's lowering ourselves to the standard of criminals, it's a deception that killing "for justice" is any more acceptable than any other kind of killing.
I'm a (very) lapsed Catholic but I do believe in evil, and I do believe in the sentiment behind "the Devils greatest trick was making people believe he didn't exist"
We succumb to committing evil deeds ourselves at our peril.
Another issue I have is that I strongly suspect that in countries that have the death penalty it's used on occasion by govts in those countries to get rid of those they consider a threat to their power by framing them for a death penalty crime. Both to eliminate and discredit them.
There's also the "what if" factor. The thought of executing an innocent person is horrifying and very much still possible. No evidence is perfect, we're only just starting to see some cases where people have been wrongly convicted on certain scientific evidence including DNA evidence. No one type of evidence or expert should be considered beyond reproach.
It doesn't work as a deterrent, it doesn't reduce costs to taxpayers, and it doesn't create more peaceful communities.
I do think the cost of keeping prisoners should be met in some way and as much as possible by the prisoner. By selling of assets and by their doing some kind of work from prison - with modern tech plus the old standbys of certain manufacturing jobs they should at least be able to contribute something to their keep.
I AM sick to the back teeth of pathetic sentencing for the most heinous crimes. At the time the abolishment of the death penalty was being discussed in uk the public were told life would mean life - that's been seriously eroded since and needs correcting! That's what is fuelling the desire in many people wanting the death penalty back in my opinion.
Murderers, rapists, paedophiles, sex traffickers and "top dog" drug dealers should get full life sentences mandatory. No ifs, bits or maybes.
"Financial" criminals - meaning those who don't directly cause personal harm - should be asset stripped, financially penalised in such a way as they pay back all they made from their crimes + interest + Costs of dealing with them (police investigation, court costs, administrating their sentence). That money may also be helpful in covering costs of prisoners and quite honestly would I think be a deterrent to those criminals who see a few years in prison as worth it for the financial reward of their crimes which they enjoy when they leave prison. Their primary motivation is money so makes sense to make the deterrent financial.
Just my thoughts
