I totally understand that. But we're talking hypothetically on this thread. The thread's about the death penalty which will never, ever be brought back in the UK. That doesn't mean we can't talk and share our perspectives on it.
Of course its emotional, we're talking about how people should be treated when they've murdered people, raped women, tortured children. You can't remove the emotion from that. No justice system ever can. Or should.
In my 'ideal scenario', these types of people would have next to zero contact with prison staff so wouldn't have the opportunity for assault.
I don't care at all about the family or friends of people who murder people, rape women, and torture children. I understand that losing their relative to a hugely punitive prison system (like I'm proposing) is hurtful. But that was the decision that their relative made. Tough.
