The term "genocide" thrown around the media is quite different than what layperson understand as genocide. They use genocide as a legal term and in that term there is also possibility that nation could genocide another nation without killing a single person - it would require resettlement actions (already happening on mass scale), denying existence of nation (Putin himself wrote essay claiming that Ukrainans aren't nation) and destroing it's identity and history (in new history books in Russia they won't mention Ukraine at all).
So yeah, even if Russia don't want to kill every single Ukrainian and genocide them in common sense, Putin definitely want to destroy Ukraine as a nation and a state that determines itself.
