When the archeologist Lawrence Keeley examined casualty rates among contemporary hunter-gatherers—which is the best picture we have of how people might have lived 10,000 years ago—he discovered that the likelihood that a man would die at the hands of another man ranged from a high of 60 percent in one tribe to 15 percent at the most peaceable end. In contrast, the chance that a European or American man would be killed by another man was less than one percent during the 20th century, a period of time that includes both world wars. If the death rate of tribal warfare had prevailed in the 20th century, there would have been two billion deaths rather than 100 million, horrible as that is.

It is good to remember that statistically things are often much much better today than 100 years ago or 200 years ago. We still have much to be ashamed of. We need to do much better for the future of humanity but in many many ways we have made great progress.
