LOL! I believe individuals humans can change but collectively, we were more or less the same years ago.
Perhaps one day we, as a species, get better but so far, I donīt think so.
*hugs back* Well, we can still dream, but you are probably right.
Yes, the story refers to humans, and it doesn't work. People generally change all the time, even if it was in bits and pieces. Some character traits get enhanced, others get reduced, but a 180 change isn't possible except in very rare cases. I think the story also talks about second chances, and we should grant them or not. I agree and disagree, as if someone consistently proved to be incapable of change shouldn't be allowed a second chance, and some transgressions are too great to be forgiven.
