IMO putting Bill or Dr. Bob up as some sort of sacred saintly person is a mistake. I'm sure they both had plenty of flaws and they knew it. All one needs to do is read Bill's introduction to As Bill Sees It he notes that:
"Of course all this material reflects my personal viewpoint on AA's way of life. As such it is bound to have its limitations and imperfections"
The program is not the person. The program of AA stands on it's merits not on the personality of it's founders.
