I think the point is not that the Society "sat down and said 'what can we do to hurt kids and protect evildoers,' " but that they made of point of trying to minimize damage to the organizational image, rather than thinking about what was best for the children involved.
In this respect, it is really almost exacty the same as the problem in the Catholic church. Church officials surely did not sit down and scheme evil to children. However, when it came time to deal with the problem, they clearly were more concerned with business matters than with the health and well-being of the victims.
From all accounts, I think it is impossible to deny that the same attitude prevailed in the Society when dealing with the problem of child abuse. Also, the general distrust of "worldy" authority figures such as police and psychologists - the people who best could have helped the victims - probably played into the problem.
Regardless of the minutiae, the fact is that the culture the Society created and maintained led directly to the child abuse epidemic in the organization.
