I think humans are largely wired similarly and it’s mostly nurture that influences one’s “moral” compass.
I don’t think our morality is evolving in any meaningful way, but I am optimistic about our ethical development as a direct result of our increasing interconnectedness via travel technology and more significantly, social media/online news.
The invasion of Ukraine, for instance, is inciting a much stronger public global reaction than international conflicts historically have and I believe even twenty years ago(or less; Crimea), nobody would have cared that some faraway place was fighting another faraway place.
I think humanity and humans individually are developing empathy past our preoccupation with the monoculture we’re born into as a direct result of physical and digital proximity. Understanding and believing that we, all humans, humanity, are all related and connected is much more difficult to ignore or discount via ignorance these days, leading to a further-reaching awareness and empathy for situations distance may otherwise have preempted.
