He was part of the system. So was Dr. Malone. The system had never betrayed them, before. The level of corruption that some of us found quite expected, they would have found unfathomable, at the start.

IMO, people like this, do deserve some deferrence. When the data didn't jive, he started taking that red pill suppository, instead of giving up, or doubling down.

As someone that had doctors give up on, or tell me very physical symptoms were all in my head, I've had decades to view the medical establishment with skepticism. The Opiate Crisis(tm) cemented my views on its corruption, long before the plandemic. Campbell had to process it in about a year. Everyone can get things wrong, and will get some things wrong. What you do about it really matters. He likely opened many minds, that would have just followed along, and prevented plenty of booster shots, as one of the fefew non-fringe dissenters.
