To address your accusations, we need to start with fundamental questions. How human civilization happened, and why some nations became richer than others?
A society needs to accumulate wealth to create a civilization. That accumulation can occur in two ways: by stronger guys extorting goods and services from the weak ones or by peaceful cooperation among equals. Looking at the past, you can see examples of the two.
But the most important is the legal structure of the society. Is it a system justifying some grabbing from others, or is it designed to protect equal rights? Then you have to realize that in both systems, the same kind of people execute them. In particular, it does not mean that all people operating within the just system are saints.
In that approach, the Western political system operates on the rules of equal rights for everyone. The Russian concept of the sphere of influence assumes that Russians can rightfully extort from others what they did not earn. You correctly point out that everywhere people with power tend to abuse it. In the West, some abusers might go unpunished, getting at most the moral condemnation. In the Russian doctrine, unlawfully taking Ukraine is their right. In their dogma, hurting others to better themselves is good. In the West, that concept is principally bad, despite not always being fully executed.
I elaborate on this subject in the following two articles:
Why do most Westerners misunderstand Russia?
Summarizing, it is easy to accuse others of biases. It takes a lot of learning to become knowledgeable.
