That guy had some balls going back into Russia, to a regime that were well known for simply doing away with anyone who disagreed with them. Even killing hundreds/thousands of innocent civilians then making it look like the work of dissidents.
We take our freedoms for granted. We get idiots bleating about a police state because of a speed limit they don't like while brave men like Navalny die for freedom of speech . And , sadly , too many of us show so little empathy for people like Navalny and his equally brave widow.
