I'm always surprised that people as smart as this guy (uni-bomber) snap, or gradually digress mentally, and do crazy stuff. Its as though they are so smart, they can't emotionally handle it and go nuts. My sister in-law is a psychiatrist, she wrote a paper on a similar topic in college and we've talked about it during holiday gatherings. It is really interesting stuff what goes on in these people's minds (at least what doctors think goes on anyway).
