Jook - I think anyone who has been/was associated for a decade or two will have come across a number of COs. Most of them are simply company men who are as indoctrinated as the rest of us were and believe they are doing something important.
Some are genuinely nice people, others are perhaps not so easy to gel with but basically OK. Some think they are on the stage and perform. Some are as dull as dishwater. At the end of the day they are just blokes doing their thing and once you check out mentally then it's easy to ignore them.
Rose on the other hand is simply a nasty bloke. He's vindictive, authoritarian and genuinely thinks apostates are scum and should be hounded out then ignored. If the WTS said it was OK to chop of the head of an apostate then Rose would be first in line to have a go. He is a hatchet man who longs to clean out under performing men from bodies of appointed men. He could not care less about circumstances, just are you doing the hours.
He confuses frankness with being a rude bastard.
You will find few people that really like him unless they are of the same mind.
