Why are people down on humanity?

As I see it, humanity’s faults are fairly consistent as the centuries go by.
But humanity’s virtues continue to expand
-empathy is recognized As a uniquely human trait
-the governed are recognized as more sovereign than the government
– the church and state are recognized as two separated interests
-slavery is recognized as immoral
-women are recognized as partners in politics and production
Etc
Etc
Etc

Like the stock market, the human virtue seems to consistently
trend upwards.
But it seems like a lot of people want to focus on fault, not virtue.
Why?
