If an entity or intelligent life form wants to do bad in any way either to others or itself, and get away with it permanently, it must:
1) Conceal the badness happened
2) The big trick though is to conceal the concealment.
This is how the collective renders it's actions into the unconscious.
It's not a perfect activity. By miracle a deep shadow can be brought into the light from time to time.
And the spell will be broken.
Paraphrase of Bohm and Krishnamurti 1980's
