Yep, according to those numbers US citizens are the most criminal in the world.
(Makes it more understandable how so many criminals end up in high positions in government.)
They might, in more ways than one, get away with murder without personally killing someone or setting someone else up to kill another. Sad set of circumstances, isn't it. But then, if I might, that's evolution.
So since it's "natural" for people to commit crimes, maybe islands filled with criminals is an answer? Where of course, the residents therein cannot get off the island.
Personally, when I was in school, and even now to an extent, I felt that free enterprise was a very unfair way to make a living. Because some became rich at a poor person's expense. Everyone cannot have it all. Some must have to have less. When they taught me about Machiavelli and the city system, I thought -- wow, that's so unfair. Now granted that many serial killers and rapists may not be too affected mentally by the idea of free enterprise, nevertheless there are murderers and then covert murderers such as those knowingly and willfully taking economic advantage of others, knowing the abject poverty that they put others in and not caring because they continue to do it. But then -- where do we go?
Only God can change things like that.
