The movie, Satan’s Little Helper, showcases a little boy, who in fact, is actually Satan himself.
The mother is Rosemary, from Rosemary’s Baby. And he is (her son) the Devil.
Throughout the film, he is trying to convince his sister to fornicate with him, by all kinds of manipulation. Such as making her feel sympathy toward him(sympathy for the devil).
In truth, it’s all a game…called Satan’s Little Helper. And the whole reason why he never fears Satan throughout the entirety of the film, is because he is Satan. The person in the “Satan” costume is actually a serial killer in a costume, trying to abuse and rape his sister. Cheers! Happy Halloween, folks.
