I'm not sure that the "common purpose" has truly been articulated; the anti-ponerocracy movement is fragmented and comes from different angles and often with different solutions. Until there is a strong bond that can unite against the divide-and-rule policies, and resist those fragmenting philosophies, I don't see the evil being cleansed.

There is also a related issue of the individual looking deeply enough to then summon the power from a pure source - this is not just physical power but mental discrimination about the relative reality of the manifested experiences.
