War is Changing process.
For russia war is just to get rid of the not needed people look how many prisoners dead in wars so goverment don't need to keep them alive.
World Changing and war is changing process Putin is just part of the other elites who do his Job that's it.
Crisis will get rid of the people who are useless for elite it's all good or bad it is how it is.
The elites are the global influencers whom may be political leaders, the Tech and business moguls that posseses the possessions of stabilizing and destabilizing the world in either security or economy challenges with it manipulative influences.
I won't make mention of anyone on the position of making chaos decisions here in this case as you made mentioned of Putin because in details to his global chaotic exhibition is that he is fighting to protect the interests of his country which which Zelensky is also reciprocating.
On the other hand, every developed and globally influential leaders are potential of setting the world ablaze which I won't exempt ones like the Putin, Donald Trumps, Elon Xi Jinping and the rest of them who has the authoritative power of controlling the militaries, Waring equipments including using the public resources for personal races.
Indeed we lives by the grace of God because we are commoners in the surface of the earth where few number of persons has dominion over multitudes.
