There really is only one explanation: Narcissism.
And he's enjoying every minute of the havoc he's causing.
I think that is part of the problem.
Long before I decided to docuмent Poche's lying, I considered that he might be intellectually impaired (e.g., congenital retardation, autism, Alzheimer's, traumatic brain injury, etc.), but his posts do not support that. His claims of speaking French and Choctaw, suggest that he is
capable of parsing and understanding language—so capable that, even in this recent post, his evasions and deceits are quite studied—only that he chooses willfully to pervert the truth.
Narcissicism does not affect intellectual function and Poche's pattern certainly fits that (I have accused him of that in his meal posts), but there is an
additional deeper problem—moral impairment.
Why does Poche remain smug instead of chastened by Matthew's studied condemnation? The usual habitual liar is not so depraved as to try enlisting St. Paul and Jesus Christ in his lies.
To infest this place with blasphemous lies requires extraordinary moral impairment, extraordinary depravity, an extraordinary enemy of the Way, the Truth, and the Life, an extraordinary enemy of Jesus Christ.
