As to his being brainwashed, he's how a lot of us are on the way out. The man spent a literal fortune and a lot of his life dedicated to a cause. The Bridge defined him for so long, it would be inhuman to just let that go instantly. I think he did an amazing job of looking at actual statistics and realizing that something is very rotten in the state of Denma--- er, Dianetics. He just made Grade 0 on the REAL Bridge to Freedom. Give him a year or two living amongst the wogbogs in the bogwogs and he'll come around the rest of the way.
