Russia is clearly attempting to annex a neighboring country through military adventurism, and is doing so in contravention with all international law, and also in a way that is intentionally cruel and borderline genocidal.

You've basically eaten Russian talking points and regurgitated them wholesale without even stopping to critically think about context.
