You should really be careful with cheap exaggerations. In the long run they will leave you without a shred of credibility. Most violent society? Are you kidding? Ever heard of Pakistan or India and the culture of rape and honour killings to the point where people march on the street to free up murderous rapists and cancel laws emancipating and protecting women? Or Papua New Guinea?
Most violent country in the world? Sure, you would be getting closer if you consider the world limited to ‘the west’ or developed world (though India gives you a run for the money out of the G20) but then you would be ridiculed as an American that considers the USA the only country in the world.
