Imagine how many lies were never corrected.
Upon these lies a lot of things may have been done, the consequences of which are, still today, based on lies.
Imagine how those small, inoffensive lies that are kept that way forever can have altered the course of the world.
Would it be better without them?
I don't know.
Many prefer the convenient lie to the inconvenient truth.
However, the advanced human should, in my opinion, always prefer the Truth, no matter what it brings with it (even if it is pain and suffering).
