why would be a fascist propaganda if they were the ones making agreements with the fascists?

Because fascists like yourself like to share this without the proper context to paint the Soviets in a bad light, when in fact it was them almost alone stoping the Holocaust.

maybe yes, maybe not, the love for genocide was mutual tho

I like how the article you shared says

Scholars continue to debate whether the human-made Soviet famine was a central act in a campaign of genocide,[159] or a tragic byproduct of rapid Soviet industrialization and the collectivization of agriculture.[76][51][17][52] Whether the Holodomor is a genocide is a significant and contentious issue in modern politics.
