That's laughable. :lol: All religions -- Christian or otherwise -- have their own idea of "natural law" and "morality."
Morality, yes, but not fully developed natural law integrated with a moral system based exclusively upon it. Every Catholic moral doctrine, as matters stand, is designed to preserve life and the social structures on which it depends.
In total, the amount of violence in the world as a whole has been falling, century by century.
As commonly cited a source as Wikipedia could show the absurdity of that statement. Look up American homicide rates in historical context, for instance.
It's remarkable that we even care about a totalitarian regime these days. That used to be all sociteties on earth...
Actually, the very concept of totalitarianism was entirely absent in the West prior to the Enlightenment you probably laud (The French Revolutionary government was the first). Totalitarianism doesn't just mean a ruler whose word is law; it means the effort of the governing power to control each and every behavior and idea, even when doing so is impractical.
-- including the heyday of your religion, which is still pretty totalitarian even now, lagging behind the secular developed secular world in many ways.
Actually, Catholicism and totalitarianism are mutually exclusive. For totalitarianism to exist, there has to be a dictator or ruling elite who believe they are entitled to do anything. A Catholic ruler would believe that mass murder, for instance, would place him in Hell.
That you have the luxury of caring about teen mothers is also remarkable. Women used to be sold into basically marital slavery in their early teens -- including by your religion.
Nothing Catholic ever "sold" women or girls, and the only slaves Catholic nations ever had were of non-white races, which is deplorable and hypocritical, but worsened (the Gulag and the Nazi concentration camps) based on purely secular ideas. What's more, Catholic clergy almost always opposed the abuse of native peoples. It was the worldly folk, after gold, who perpetrated such deeds.
Fornication has always been common...
That wouldn't even be possible. Without artificial contraception, widespread fornication would have led to widespread pregnancy and thereby to widespread abortion, which would have been fatal on a species-endangering scale to women had it been "common".
Again, that wouldn't even have been possible. Women could not have supported themselves in medieval times, for instance, without husbands, and no man could have been a single father, with the amount of labor he needed to put in, without a wife to nurture the children.
If it is true that only the religious are "good," then explain to me why the more secular a country is and the fewer religious people it has, the better, more peacefully, and more intellectual its society is. All of the top countries of the developed world by metrics of crime, health, poverty, education, etc, are at least half non-religious, and many are majority non-religious.
Your notion of "intellectual" as good is amusing, because it's intellectuals who unfailingly bring about the greatest ruin (Marx and the Aryan Supremacy theorists of the 19th century were intellectuals, for instance). As for the rest of it, you're apparently unfamiliar with the sexual assault rate in Sweden or the suicide rate in Japan, to cite two examples. Moreover, other than Communist nations, in which professing atheism is mandatory, the only country with half or more of the people non-religious is Japan, so unless you're saying that China and North Korea are at the forefront of said statistics, I would say you must read nothing but atheist propaganda.
Crime is most common in impoverished areas, BUT when countries do become wealthy and then also become less religious (which is by no means cause and effect), their crime rate goes up and their families break apart, which leads to a disintegration in all the other metrics you mention.
