USA Murder rate 1948 : 5.9 vs 4.9 (2015 aka now) I don't know about you but I would call Murder a rather extreme unethical behavior. https://en.wikipedia.org/wiki/List_of_countries_by_intention...

Now, compare with say France a very secular and minimally religious country and their murder rate is 1.31 (Though not 100% apples to apples this extends across many other similar statistics.) : http://www.nationmaster.com/country-info/compare/France/Unit...

Surprisingly China and Japan perhaps the most atheist countries out there with significantly different economic situations also have lower murder rates than France. (Though again not apples to apples statistics.)

PS: I often hear about morality religion links but only see a few meaningless connections like church attendance and divorce rates.
