"No knowledge in Kamar-Taj is forbidden. Only certain practices."

You reminded me of that quote from the Doctor Strange movie.

Even the most "dangerous" knowledge can be life-saving, depending on the circumstances. When I was a teenager, I read the Terrorist's Handbook, which was a text file circulating on bulletin boards. After 9/11 it vanished, because posession was considered a crime in some jurisdictions.

Knowing how to build a bomb is useless and/or dangerous in civilian life. Ask a Ukrainian if it is useful knowledge!

Knowing all about nuclear weapons doesn't mean you're going to blow up a city. But if someone else does, then you'll have the knowledge needed to avoid the worst of the radiation and maybe survive.
