hmm not sure how we can say "developed a deeply ingrained sense of right and wrong" , in last 100 years or so religion is in decline ; and its not playing a significant role in politics, economics, .. but yet we are still able to kill millions in world wars and even after that in the name of freedom , democracy, .. but eventually destroying those lands, those people and their culture

And able to produce characters like Hiltler, Staling , Mao, .. (who are not religious motivated) ; why did they killed millions? Why no body tried to stop them? ( is Morality needs to be practiced or just a bookish thing)

We are on the verge of climate catastrophe because of capitalism ( which only appeal to our vulture instincts of acquiring more at the expense of other people , nature and our own future) and we have the highest form of inequality between masses ( .01 % vs the rest) ; do we care about a child or human dying in Africa of hunger/war compared to a person dying in West? why is that, does morality differs when you are born at a certain place ?
