If Satan himself proves a theorem, is it nevertheless a true theorem? Claims are either true or they are false. There is no such thing as an evil truth. Where are the breaches?
But don't you understand? The aim wasn't to prevent the breaches that would inevitably happen on day one; it was to prevent the breaches that would happen after that fact. Without mobilising everyone and getting people to patch through an event, we'd be in a far worse position.
The greatest trick that Devil performed was convincing people that he didn't exist, right?
