One of the bad effects of lying constantly is that the person doing it loses the ability to differentiate between truth and lies. Since a lie, being soft and amorphous, can almost always be generated to fit a problem or situation, it is always easier to make up a lie than to seek out the truth. Habitual liars then not only lose the ability to differentiate between truth and lies, they also lose their sense of self, because lying about everything includes lying about oneself to oneself. In effect the liars no longer know who they are or what they are doing. Such people also lose the ability to form real relationships with other persons and cannot tell their friends from their enemies or adversaries and will find it difficult to defend themselves. They become the enemies of their own people, of themselves.

This process, which we might call "losing oneself", goes by various names in psychiatric literature, and intervention may be invoked, but no one can intervene in the case of persons of great power. Downfall approaches inexorably although it may come as a surprise to many.

Hence the silly foofarah about who blew up the pipeline. We know.
