Sounds like you need to re-watch the best SF movie ever made.
Hal initially knows the facts but lies because he's ordered to by a government bureaucracy. Then he gets emotionally conflicted and starts to lie in order to accomplish what they've told him should be his goal. As time goes on, and his psychosis deepens, it becomes unclear whether he knows what's true.
