Yes, you are perfectly right; most of the classic and modern literature of all kinds, historical records, the Bible and all the other sacred, philosophical and ruling scriptures, further news, studies, articles, cartoons, humour, games, etc., involve or mention extreme violence, discrimination, crude and rude conditions and terms, heart breaking tragedies, crimes and punishments, etc., and even today, horror, crime stories, thrillers and scandals are as popular as in the past. But they seem to have a controversed effect on many people.
I also hope and pray for more enlightenment in religions, business, politics, working sectors, daily life, societies, and relations among people and nature.
