Does sibling rivalry explain how people in cults like Mormons and Jehovah's Witnesses rat each other out?

Remember what is was like when you were a kid and your sibling would rat you out to your mom or dad if you did something wrong? Well, that's exactly what it's like if you join one of these sinister cults. The people in these cults have a childlike mentality and they see their cult leaders as parental figures. They see their fellow cult members as siblings and they get jealous if their fellow cult members get more attention from their "parents." So there is all this petty bickering and ratting each other out that goes on in these cults, just like annoying snot-nosed little brats informing on each other. Do you think this explains what goes on in these sinister cults?
