“This is worth knowing. Because, if you are preyed-upon by a psychopath - which you will be, to some extent, at some point in Your Life - The Psychopath will assume that you’re stupid and that you deserve to be taken advantage-of, because you’re naive and stupid, so it’s actually a good thing that he’s doing it.
The proof that you are stupid-naive is that he can take advantage of you. And so, if you were wiser, you would know his tricks and it wouldn’t be morally necessary for him to show you just exactly Who Knows What about What.”
