Surveillance is blind to minor transgressions, supporting the idea that you can slight people and be a crappy human without consequences, and it is also far from omniscient, and can be specifically blind under circumstances that you may control. More so it can be wielded against other people by creating “scenes” that promote a narrative that harms them. It is not an judge of character, but rather of appearances.
Of course the fox is to install a strong moral character in the home, by way of teaching rather than training, but unfortunately many parents give similar attention to their children as they would a beloved pet, so that is not at all something that can be expected.
