The reason HAL went nuts (given in 2010) is that they asked him to compartmentalize his data, but still be as helpful as possible:

> Dr. Chandra discovers that HAL's crisis was caused by a programming contradiction: he was constructed for "the accurate processing of information without distortion or concealment", yet his orders, directly from Dr. Heywood Floyd at the National Council on Astronautics, required him to keep the discovery of the Monolith TMA-1 a secret for reasons of national security. -- Wikipedia.

Just saying.
