The point is exactly that the shittiness seems decreasing on the historical scale, albeit very slowly.
Compare e.g. Moses and Hitler. Both of them became famous for being leaders who demonized their enemies and tried to exterminate them to the last one. Yet the latter is considered the archetype of evil, because he did the thing during the 20th century, when we expected people to do better. The former is considered a holy man by multiple religions, and his violent actions are not considered a stain on his character, because “back then, everyone was like that”.
