I wish we could implement your solution when it comes to war. The way to make war less deadly and terrible is to not fight wars, these guns don't fire themselves. If only life was so simple. You may say it is a bad argument as war depends on others, not just oneself, but in many instances of death cap mushroom poisoning, the victims are not the ones who picked and prepared the mushrooms, do they deserve death too?
