Who cares which GB was worse. They both abuse authority, take advantage of people mentally, physically, emotionally, and financially.
It's like trying to decide which rapist is the least moral.
As far as the r&f blame goes, I think it is definitely a case by case situation. Some know more than others. Some are more capable of thinking for themselves than others are.
Actually when I think about some of the people in my hall, it is disgusting how the GB (of whatever flavor/time period) have convinced many simple-minded people to dedicate their entire life energy to the organization. They really believe they are pioneering for God.
Also, the fear of being ostracized is a huge deal. The leaders create an exclusive community, engender dependence by talking people into cutting off any other sources of support, and then threaten to rip it out from under them if they dare step out of line. It is truly sick and psychopathic.
It's a hard hard hard reality to face. Even harder for born-ins who have barely any connections/relationships/support/family etc. outside the org.
Imagine waking up in the Truman Show as a middle-aged person. No wonder so many get on mind-numbing drugs and bury their heads in the sand.
