I couldn't understand some of what they guy was saying, and my Pavlovian response from the first second of footage was that it was more professionally designed than one would expect from a spontaneous quicky vid.  But it certainly could be.  Anyway...

Asking if Azov in Mariupol committed war crimes is absurd to me, but not fully though because there is an element of personal ethics which can vary from person to person, philosophical framework to philosophical framework, etc.  Although not religious, I grew up in a Christian country with 'Christian ethics' so the use of human shields is about as bad as it gets irrespective of what one law or convention may or may not say.  Were I of the 'means justify the ends' philosophy, I might be of a different opinion generally although I think that most things construed as 'Nazi ideology' have pretty bad 'ends' as well.

There seems to be a religious ideology which may be more common than most people think.  It is to actively make the world so filled with such vile behavior that God(s) will be compelled come back to straighten things out.  I suspect that it appeals to people who have a propensity for degeneracy of one form or another anyway.  Like Nazis, Bolsheviks, Maoist, some groups of doctors and scientists, etc.  This seems to be the attitude promoted by many Kabbalists (especially the ethnic supremacist ones), and at least tolerated by garden variety Luciferians.  It seems to me the best match for what we see going on in Ukraine these days, and yes, driven mostly by the Ukrainian (sponsor's) side.

Yes, I certainly consider the Azov guys to be 'just a gang of terrorists' from all that I can see when I try to be objective, but the people who built and control them (at least partially) are even worse.  Unfortunately that is in large part my own government since I still hold a U.S. passport and pay taxes through that entity.
