Our last CO was like that, he removed many elders and servants and was a bully and so codescending. Before I "turned to the darkside" at one of his last visits he handled something incorrectly according to WT policy he tried to tear me a new one.... but when I handed him the elder letter (I was the Secretary at the time) he just looked at it and said "you can write service if you want but what we decided stands". Later I learned that he was bad mouthing me to the other elders trying instigate me to be deleted, thinking back I wished it had happened so I wouldnt be one anymore, but the other elders didnt like him either so they didnt agree.
The next one after him was every bit as controlling but in a more subtle way...kind of like Darth Sidious if you watched the latest Star Wars movies. He would act behind the scenes manipulating elders to put people in to service commitee positions and suggest things during our mtgs but fall short of actually saying we had to go along but we all knew what he wanted and did it. He was so cunning that most of the elders in my hall were seduced to follow him and they were rewarded for their ass kissing with assembly parts.
Now we have a new one, older man, and seems to be a company man but very to the point. Doesnt want to hassle with anything, just wants to do his job and leave. I guess they all have different personalities but to me the most hypocritical and dangerous is the second one I mentioned... the ones manipulating behind the scenes.
