Why some humans are so evil: double standards and irreligion

[FatAndFaithless]

But those old bad times you reference..those only changed because people weren't bound by their circumstance. Obviously people saw the things wrong in their current time, current society, so they changed them. The world keeps getting better and better overall (there's always going to be dips, of course), but people always think it's getting worse and worse.

We aren't just bound by a chance of being born in this time and place. People have agency and ability to break from whatever the norm is. And in general, most people most of the time use that agency to improve things.
