I understand what you're driving at, but I think war is actually a pretty good example of something that's become significantly worse over time. It used to be fought on a small scale. The biggest battles had just a few thousand casualties. Today, war is total, nothing is off-limits, and global conflicts reach levels of destruction unimaginable in the 15th century. And a few nations possess enough firepower, in nuclear and conventional form, to essentially end human existence on earth if they choose.
