There are many characters in “Star Wars” who don’t act out of malice, necessarily, but they still do small acts of pure evil that end up having big consequences. One of those characters is Jocasta Nu.

You remember Jocasta, right? The Chief Librarian of the Archives, and former member of the Jedi High Council, first appeared in “Star Wars: Attack of the Clones” as the keeper of Jedi knowledge, and helper to those who seek to learn more. Except that is not at all what she did in her brief appearance in the films. Instead, when Obi-Wan Kenobi asks her for help identifying the planet Kamino and it doesn’t show up in the archives, she immediately mocks him and tells him the planet must not exist.

That is not just bad librarian behavior but had this woman simply cared a teeny tiny bit more about the issue, they could have uncovered the clone plot sooner. Because she didn’t care, Kenobi had to look into things on his own, then get captured, and force the Jedi to use the clone army they didn’t know they had to rescue him — kickstarting the Clone Wars and eventually the fall of the Republic. Is Jocasta Nu as bad as, say, Vader? No, but this Hologram-book jockey is still pretty evil.
