Well said. The "Human Animal" has a "dark side" which only needs a suitable environment where it is condoned without repercussions for it to flourish. In a small group (eg. a Village) since every person is personally identifiable these "animal" tendencies can be kept in check by a suitable environment. But in a larger group (eg. a City) because of the power of anonymity rules can be broken without repercussions. "Cyber Bullying" is another very good example. "Normal" people say the vilest of things due to the psychological distance involved and lack of personal repercussions on the Internet.

In a way, i think B.F.Skinner's "Behaviorism/Operant Conditioning" was exactly right as regards "Human Nature" but sadly people don't want to give up their utopian fancies.
