But should the state be in the business of executing such people?
Honestly I've always felt this was the strongest argument against a death penalty. That said the argument carries nearly the same weight for life imprisonment, and still some for the act of imprisonment at all. We continue to trust juries of fools to judge people to this day, but that is still unfortunately more palatable than giving the right to someone to unilaterally choose your jury.
I'm onboard with a culture of reform and education for convicts because it works, but I also recognize some people cannot be reformed and keeping them imprisoned is needlessly dangerous for many parties. There needs to be a line where we accept someone is too far gone.
