Death and destruction has always been fascinating–for observers, not participants. Crucifixion, hanging–especially when accompanied by drawing and quartering, and beheadings of any type have always been crowd pleasers. The brutality of man against man could draw a crowd, amuse it, and leave it calling for more.
In your twentieth century, there was the term “like watching a train wreck.” It’s nigh on impossible for anyone to turn away because a train wreck is factually as well as literally, extraordinary.
I understand that. I may not approve, but I understand it. The observers don’t set out with the intent of seeing carnage, but happen to be there when it does.
On the other hand, when Facebook (which I also do not understand) has to remove 1.5 million–MILLION–videos showing the slaughter of people trying to pray in New Zealand, I’m astounded. Actually, I’m disgusted. A man who lived in a sewer and treated others the way I did is not easily disgusted.
In the millennia from my time to yours, it would be reasonable to expect to see some small amount of societal progress. Instead, people in the twenty-first century can easily put Emperors Tiberius, Nero, and Caligula to shame.
