Yes, although whether or not we find humour in that kind of stuff is is heavily nuanced and context-dependent, even within the narrow genre of kiddie rape and murder.
I think the reason Maddie is such a comedy goldmine is because of the whole circus surrounding the case, and the fact that her white middle class parents blatantly killed her, which *is* inherently funny.
There are other cases where small children were brutally murdered that you'd struggle to find any humour in.
You don't hear any jokes about Jamie Bulger, for example.
This is what's known in some quarters as 'Whataboutery', I gather.
Besides, there have been left-wing governments who have not been run by Stalin, and not behaved remotely like him, however much they are demonised, and however much the oligarchs are furious that the wealth they nicked from the poor is redistributed to the poor.
That's right, those magnificent shining examples of the gentle loving nature of socialists, Mao, Pol Pot, Uncle Ho, dear Nicolae in Romania, cuddly Enver who made Albania such a paradise of redistributed wealth - and let's not forget our old chum Castro, who cleverly reduced and entire population to penury and locked them in so they had to try to escape on home-made rafts.
Were all these the wrong type of socialism?
