Why do people need to make shit up about Stalin to slander him? He did plenty of real bad things, like deporting
Chechen people and
Kalmyk people to Siberia as collective punishment for instance, an action which killed thousands of innocent civilians, or forcefully collectivizing or resettling various populations in part of the country, or sending monks, priests and imams to the Gulags merely for being religious functionaries alongside anyone with the bad luck of being seen as a Trot or some other "political undesirable" (often whether or not the suspicions of being in the opposition were well-grounded, of course).
as for the question in the OP, Stalin was pretty much the pioneer of the cult of personality so yeah i'd expect this kind of thing in soviet schools
