If we are executing enough people that capital punishment duty is actually a meaningful way to acquaint people with the gravity of taking another person's life

If we are executing enough people that capital punishment duty is actually a meaningful way to acquaint people with the gravity of taking another person's life in the name of justice, then our society is already repugnantly sick and violent. I think we are some distance from that, and I'd rather not move closer. Furthermore, I think the risk of such an experiment is that we desensitize the population to the taking of human life.
