Pavlik Morozov is the subject of an infamous propaganda campaign in the Soviet Union about a boy who allegedly turned in his father, then he was reported to have been murdered by his family and the state made him martyr. The reason for denouncing his father varied based on what the party thought was the most pressing issue at the time and place when telling the story. Stalin is said to have called the boy a "little swine" in private for betraying his father.

Nearly all children nowadays were horrible. What was worst of all was that by means of such organizations as the Spies they were systematically turned into ungovernable little savages, and yet this produced in them no tendency whatever to rebel against the discipline of the Party. On the contrary, they adored the Party and everything connected with it. The songs, the processions, the banners, the hiking, the drilling with dummy rifles, the yelling of slogans, the worship of Big Brother — it was all a sort of glorious game to them. All their ferocity was turned outwards, against the enemies of the State, against foreigners, traitors, saboteurs, thought-criminals. It was almost normal for people over thirty to be frightened of their own children. And with good reason, for hardly a week passed in which The Times did not carry a paragraph describing how some eavesdropping little sneak — ’child hero’ was the phrase generally used — had overheard some compromising remark and denounced its parents to the Thought Police.
