Human nature is many things. Among the most important of its components:
a) The further from destitution we are removed the lazier we become. It was not long ago, perhaps 300 years, that the vast majority of humans were engaged in agriculture in some form or other. We had to make sure we had enough to eat. Now, far removed from any threat of starvation, at least in the West, we are a fat, lazy and entitled civilization.
b) The further we get from an embarrassing or troubling event the smaller its impact on our behavior. Our heart-felt apologies and pledges to never do "that" again lose their urgency and so the old event has an ever decreasing impact on our current behavior.
c) Honesty and integrity are highly valued characteristics. Like so many things of great value, diamonds, gold and beauty, for example, they are in short supply. Be honest, have integrity and you will be highly valued. I do not mean this in a monetized way, although that may come to pass.
