Dark Side of the Force/Web/End of 2.1

As Star Wars III came out, one of my friends spolied it by telling me, "Anakin becomes Darth Vader."  For all the good things that the web or information or books have to offer, there are those who will use them with malicious intent or to scam or to hurt.  This is not new to the web and its technology, but indicative of human nature.  How do we know how noble Othello is without Iago?   We can only hope to proceed with caution without limiting ourselves from exploring how these new technogies may dramatically change the world in which we live.
