Everywhere but in the manicured shelter of civilization. The recent history of Russia reminds us of how order can descend into chaos with just a few twists of economical-political fate. The underlying, and perhaps unanswerable, question of why some men turn into sadistic bullies, is where the real problem is.

The deeper work of eliminating cruelty and instilling kindness depends on many things.
