Who will perform these executions? As it is, 100% of interviewed former death pentaly workers, who administer the death penalty to convicted criminals (aka "bad guys"), went into the job being for the death penalty and then left the job being against it. Quite unlike humane euthanasia providors for hospice patients, may I add - it isn't just the death causing this. I can't imagine what workers would even be willing to do such a thing. And before you say "psychopaths" - the death penalty workers def had at least 1 or more psychopaths, psyopaths can understand rationale and logic and cognitive empathy.
