MKULTRA and all US-based human experimentation and study projects done both on their own citizen and foreigners from other (complicit) countries are quite a trip to read through. One would assume the government pouring so much money and man-effort into these researches would make ruthless individuals feel more justified in committing their overlooked, state-mandated crimes. Of course, being a sensitive, secretive and very speculative subject it's important not to take everything at face value, as there's an abundance of theories and the emotional impact can make one overlook logic. There's really a lot of interesting ones. Familiar with a certain Kaczynski?
