I understand that, but it's reasonable to suspect that for a significant number of #2s, #1 is the initial motivating factor that got them learning. We see this all the time in software development, where excellent engineers are borne of trying to build a video game at age x, where x is a relatively low number. Similarly, there's no reason that someone initially motivated to eradicate "evil" can't become a great security mind, and I suspect Moxie and many like him are of this ilk.
