No. What happens is that in modern times, we find people in societies that behave in the most stranges ways. We can think that people that live in modern societies have a certain degree of formal education, behave themselves according to social patterns and traditions that are expected by other members of society, and show respect and tolerance to other people that think and act differently.
However, as we see it on the news, barbaric conducts are common in modern societies. Even worse than the barbaric behaviors we could expect to see from "uncivilized" people. They have to survive in the wild, that is why they seem to act "uncivilized." But educated or modern people, well, they are supposed to be the educated ones. And many times we are not seeing that by the way they act or react to confront daily situations.
