Very good questions to ask, though I'm not sure it's a valid premise. Can we measure or track morality similar to technical progress? How could we really know that we're on a "right" or "wrong" track on morality? We could say, "If we kill less of each other, we are on the right track" but how do we know that what might appear a small morale roadblock isn't setting us towards progress? For example: At first blush Hiroshima looked awful, though even there we had some ambiguity as generals defended national interest. But what if the experience in Hiroshima allowed us to keep our wits and not escalate Korea, Vietnam or Afghanistan into a nuclear war? There's no way to know if we made morale progress. But I do like the question, which is, "How can we make sure we're increasing our ability to get along with each other, as we develop better weapons to hurt each other with?"
