I don’t mean to start a discussion here, but this is your interpretation and it’s valid. But galadriel’s character has contradictory history depending on your sources (even regarding the kinslaying). And it’s debated even between Tolkien’s scholars the extend at which she can ‘sense evil’. After all, she herself was deceived by saruman after his corruption during the third age.

In your last paragraph you say ‘nothing about her character in the series has any respect for Tolkien’s work’. That’s simply hyperbole, and arguably not true, as even a surface level reading can prove otherwise. Such words are not Tolkien’s way.

Anyway, I don’t want you to change your mind, just want you to be aware of the possibility of other interpretations. Take care!
