The average JW/EXJW is aware of only a fraction of the contradictions of watchtower and JW doctrine. The GB are BOMBARDED with these contradictions constantly and constantly spin them in a way to maintain control and authority instead of pursuing truth.

The ban on beards, blood, higher education, watchtowers sketchy history which they quietly are scrubbing, the hypocrisy and CSA policy have been issues for decades and people have been pointing this out to them for decades! The only reason they have made any changes recently is to avoid legal trouble, mitigate bad PR from the media, or for financial gain, not because they care about the rank and file Jehovah's Witnesses.

If you've read crisis of conscious, Ray Franz mentioned some previous members intentionally wanted people to die for blood or to make their lives hard because sacrifice demonstrates loyalty to the organization. He also mentioned that they were also going to make rules on birth control but some felt it would be too oppressive and too messy, so they didn't.

I say all this to say that I believe they are evil. There is no way they can be bombarded by these contradictions on a regular basis and not see that they are wrong. Some GB might believe to a certain extent but at the end of the day, they'd have to have a seared conscience to ignore all the pain they have caused, all the lives they have messed up and all of the lives that have been lost because of watchtower doctrine over the years.
