I appreciate the comment, but respectfully disagree with your conclusion. You can’t really “debunk” the notion that when it comes to murder specifically, justice necessitates an execution. You can disagree with that belief (as I do), and you can make some very persuasive arguments against it (as I often try to do), but you can’t disprove it in the same way that you can disprove flat-Earth theory or anti-vaccine propaganda.
