It's sadistic.
When "a grad" tries to follow all the "rules" and, predictably fails, "the leader" is getting pleasure from that futility.
When "a grad" realizes they are on a fools errand and speaks out, "the leader" gets a kick out of that, too. . . Cause there will be no remorse.
The slippery (pun filled) language is chaos for chaos sake. There is no desire to communicate anything of substance. Just generate something that looks like a conversation . . . For the sake of angst, frustration, suffering.
