As close as I can tell, Russians tend to be very fatalistic. It's never been a happy place. It's cold, the state is corrupt, life is cheap. But people have a strong personal need for justice, to find those guilty and make them pay. But the state won't deliver justice, so you make a stand, and life is cheap so you take risks and double down. Hence Navalny, hence Litvinenko, hence all the journalists over the years who reported until they were thrown out windows or gunned down in public. Incredibly brave, I only wish the bravery led to real change rather than a neverending Greek tragedy.
