With the knowledge I understood it as having universal excessive knowledge can bring you to madness, hence, it's bad. Not as knowledge is bad per se.

I know, I got that. (Me making fun of the NBC logo and stuff was just taking the piss out of the manga for the sake of taking the piss out of the manga.) But my objection is still this: IRL there is no such thing as universal excessive knowledge. So Ohkubo creating this fantasy-world problem about the dangers of humans knowing things that they were never meant to know is just about the most shallow approach to the "insanity of knowledge" that he could take. There are other ways that he could have cast the problem - i.e. the dangers of knowledge imparted from on high instead of earned, or the dangers of pursuing knowledge at the cost of morals and ethics - but he went for the least interesting approach possible instead.

Like I said, it's not a problem that I find compelling because "knowing too much" is never a problem that can exist in reality. It's not like the way that Ohkubo presented the insanity of power or the insanity of order - clearly problems that are universal to humanity and therefore, you know, interesting things to tackle as conflicts in a fantasy manga.

And yeah, Soul Eater Not! is pretty awesome.
