The suggestion that absolute power tends to corrupt has an interesting corollary that stems from an observation from an objective viewpoint. Viewing ‘good’ and ‘evil’ objectively (ie in conflict we cannot definitely choose who is good or evil), there is the suggestion that the ‘evil’ side TOO will have this problem with corruption.
So in regard to corruption of a few in a population of otherwise good peoples, there is the corollary that in a population of bad players there will exist the tendency of a few to defect and do “good”.
These would be our “whistle-blowers” like Snowden.
And so then these organizations that are corrupt and need whistle blowing, will always fail if they have any significantly increasing power or security leaks whatsoever.
