I only put this on the gun thread because that usually is the context of the topic of murder - and to not clutter the top of the board with it.
Is it possible that the more freedom people have and the more wealth and economic opportunity there is - does this somehow inevitably result in higher murder rates?
Thru all of history there has always been genocidal, psychotic, sociopathic, psychologically disturbed and/or sadist people who commit senseless murders for which regardless of motive, there is a desire to commit murder, indiscriminate murder and mass murder. That somehow that is in human genetics to some degree or another, some percentage or another - and the question is how much can a person control the desire - and how strong is that desire?
If a person feels "free," they feel free to think freely - and may have a greatly heightened sense of unfairness and seeing themselves as a victim including by society. If things are fair, why is everyone and everything so unfair to him. If everyone has so much opportunity, why doesn't he? He can develop this personae further and further from reality on social media. If added to this is a reclusive and regressive personality leading to social isolation, everyone he blames - other students, society, people of some race or religion or other religion, a certain gender, some political reason, type of music they like - whatever - the element of freedom and national prosperity - becomes the focus of his intensifying desire to commit murder.
I bet the murder rate (excluding by government) is much lower in North Korea and China where people are less free and have less hope of great personal career choice and economic prosperity.
Is one of the prices of freedom and wealth of a nation that this inherently lends itself to a higher murder rate?
