FullWings, I believe you to be correct and, over the years, have observed the same behaviour in some of the captains I flew with. When it comes to trainers, some people wanted to become trainers in an attempt, albeit unwittingly, to compensate for these aspects of their characters and also because they wanted power. In a past life I used to sit on selection boards selecting new trainers. It was incredibly difficult to differentiate between those with the wrong motivation, but who could 'interview well', versus those who really wanted to help people and who had the right empathy and analytical skills to become a good trainer. It was not easy and I know we got it wrong too many times.
