I saw someone saying that many want to assign values of nobility to many Russian decisions that can really be boiled down to just wanting savagery. That is probably not entirely fair, but I would say it is in the case of Putin and a number of other leaders before him. We see that over and over with so many in the West who hate their countries and cling to Putin as some embattled hero fighting for their future, only for him to say, over and over, it's not about any of that - he just wants to conquer and conquer and conquer.
There is not going to be any moment of uprising or reckoning for Putin, especially not from his own people. I can understand why Navalny, who likely knew he and his family were facing death if he did stay away, may have wanted to return and possibly be part of that change, even at cost of his own life, but it won't happen. Putin waged decimation against millions of Ukranians and yet so many inside and outside of Russia still cheer him all the way.
