The NSA is a huge place, you saw only a small segment. Their primary role is to spy on US and international citizens and make sure that nothing diabolical is going on. PRISM (and other programs revealed by Snowden) showed that they have no qualms about violating the Constitution and privacy rights of citizen in pursuit of their job. I am sure there are lots of good people at the NSA just working 9 to 5 feeding their families, however don't overlook that their job is to spy on anything and everything that is going across the internet in order to look for threats to the country, whether it is constitutional or not.
