I only want to say which connectivity I think I found between the two stories... I don't know if it's what Pasolini wanted to say (if he wanted to say anything) but it's just a possibility...
I think it's clear that Julian, the son of the former nazi, has that personality for two reasons: he is very intelligent and he's father is the kind of person he hates more in the world; but it's his father (That's very similar in the novel "Gracias por el fuego", from Mario Benedetti, in Spanish). Julian is very afraid of knowing himself, because it means hate his father. Julian is a socialist person (he has his 50% revolutionary slept, but he has it), and his father is the main guilts of the social injustice in his closest world. As well, he thinks he can't have any horizontal relationship with any person in the world, because he thinks he's different, maybe better, or at less more intelligent...
The other story represents what Julian should have done, for Pasolini, to find the happiness. "I killed my father, I ate human flesh, and I quiver with joy.". The only way he could have to be himself was killing his own father, the former nazi (again like "Gracias por el fuego"), and to look down of all the people (represented like eating human flesh). Then he would started to quiver with joy... but, for me, in a fake happiness resulted from a failure...
