Years ago, I remember reading a book with a plotline that included a small group of people putting together a nuclear bomb. Don't remember the book or the author, but I do remember the author's note at the end. It said: "I have changed some details about how to put together a nuclear bomb. I did this solely as a salve for my conscience, not in any reasonable expectation that it matters a damn."

That's pretty much my take on any of this stuff. The world is full of people who can't or won't make sure they are teaching only bona fide good guys. Worry about it, or don't, based on your own conscience.
