(4) is an example of petitio principii (aka logical fallacy of begging the question)
Naming something with a fancy Latin term, without explaining what you mean, is an example of intellectual snobbery...
From the article, especially since Michael could start and stop his tantrums at will... it did appear that he was manipulating his parents (even if for childish, nonsensical-to-adults reasons).
Although the writer indicated the mother was strict, no-where did it indicate that Michael consistently received any serious consequences for his terrible behavior. Should he get spanks for every infraction? Of course not, but willful disobedience....needs serious consequences.
The calm “I hate him” and other creepy behavior made me suspect not merely lack of discipline (i.e. spankings) is at work here, but possibly the occult.
