The First Law Question.

[Moriden]

I disagree, because the knowledge on its own shouldn't ever be corrupting, only acting on it.

Many, Many metaphysical schools of thought profoundly disagree with this, they state that there is certain knowledge that simply having will cause you "damage" it is strongly portrayed that any level of understanding about the outsiders is this type of knowledge. Am example from a completly differnt setting/ game system would be wyrm lore from the owod, simply haveing even one level of it could give you a permenent derangement[ drive you insane]

Since Butcher has implied that the Outsiders are akin to Lovecraftian horrors, I wouldn't be surprised if mere knowledge of them made you insane. It's Cthulhu Mythos canon that just reading the Necronomicon damages your mind after all.
