But unlike the other powers, ComStar claimed an essentially benevolent mission - and technically never claimed that they should rule the Inner Sphere. That's the ComStar the new recruits signed up for. And on this basis, despite all the religious trappings and upper-level corruption, I tend to regard 99.999% of all ComStar personnell as people who genuinely tried to be good, fair and unbiased towards everybody.
That's excluding certain high-profile leaders, of course, and by extension the organisation as such. But Acolythe Joe Average, almost certainly, was a good guy because he wanted to be.
