Assuming the scandal was pre-initiation, i would presume because he did not have a serious conviction, was seen as fulfilling prerequisites, had propsers, was not blackballed.
Im not surprised someone replied to your absolute statement about all Freemasons being good. Every barrel will have its bad apples.
Quite right too, hence my trepidation at the end of the post.
Thing is in my jurisdiction every mason I have met have been at least decent to me, beyond that I couldn’t really care.
The way people choose to live their lives is their business and as long as their behaviour that I have experienced is decent they are fine in my books as that’s all I expect from them, im not in a position to be passing judgment on anyone so I just handle my own affairs and should someone ask for help I’ll assess the request on its merit.
If you get hung up on people not behaving the way you feel they should you are in for a life of disappointment.
