Ah, and there it is again. EWhen confronted with a clear and obvious Denkfehler, a massive flaw in the Western propaganda narrative, you just fall back on the weak-ass argument, "because Putin is crazy and/or evil".
So Putin's goal all alomg was to kill as many Russian soldiers and ethnic Russians in the Donbas as possible, right?
And the best way to accomplish that goal was to sit back and watch the US and NATO arm, train and prepare Ukraine to fight a war with Russia?
Of course the Russians blew up Nord Stream 2, because they are "crazy" and want to "embarrass the West".
They blew up the Kakhovka Dam because they wanted to cut off water to Crimea and destroy the ethnic Russian cities and farms and villages in that region.
Because they are evil and genocidal, and Putin is hell-bent on killing as many of his own people as possible.
It was actually Putin and the Russians who were shelling and killing civilians in Donetsk and Luhansk all those years. Again, because Putin is evil and crazy and you cannot ascribe any sort of logic to him.
The Russians, according to your narrative, cannot help themselves - they are so evil, crazy and stupid that they just keep on doing things that hurt themselves and just happen - accidentally - to help Ukraine.
