You do realize that we are on the verge of a nuclear holocaust? And for what? It is certainly not for the well-being of the people who live in Ukraine. Do not try to kid yourself. It has never been about their best interests. They voted for Zelensky because he promised peace and prosperity. The people behind the scenes who actually orchestrated his rise to power never wanted that. The Ukrainian people were duped.
And you are gleefully making predictions about Russian's fleeing to China for warmth? The Russians and their leadership were duped as well. Look further into the roots of how this has developed, and you will find a lot of sinful hands had already been stirring the pot for years before Joe (We won't do anything if it's a minor incursion) Biden and company basically encouraged the Russians to take the action that they finally did.
The true instigators of this mess worked for decades to pry Ukraine out of the sphere of Russian influence and when they finally were successful it took less than ten years to foment a full-scale conflict. The goal has always been to destabilize Russia's government to create more economic opportunities for the oligarchs and leaders of countries with failing economies who somehow always seem to profit from conflicts that create mass scale death and misery for others.
So yes, I agree that “Sin eventually devours itself.” I am not sure that you realize that the sins and the sinners may not be who and what you think that they are. The price to be paid may also turn out to be much worse than you seem to imagine.
