There is a LOT of ghastly business in the historical record. Not sure current events are even as bad, and certainly not worse. The first war of the Industrial age (AKA, “the Great War” or WWI after there was a WWII) killed (conservatively) 15 million people. And that from a total world population only a quarter what we have today.

Few of our predecessors actually had it this good really, which of course is little comfort to those that are being affected.
