Only if you wish to persist a violent system aiming to wreck lives. We could instead try to help everyone involved heal from the event(s) and initiate processes to uncover systemic issues leading to them. I'd rather the latter.
I predict that I’m in the minority in believing what I’m about to say: In the unlikely event that it turned out the best way of minimising homicide was to promise every single convict £1 million and a 12 hour episode television show in their name, if that actually minimised homicide, I’d be in favour of that response to it. I will of course freely admit that the reason I can say something so shocking is because I don’t know anyone who’s been murdered.
I care about minimising the aggregate rate of all homicide, not punishment for it’s own sake.
