She is a psychopath - not psychotic. As such she has woven her fantasy into her reality. She 'knows' it isn't the truth but instead of revealing the actual truth, which would send her to death row, she will instead roll the dice and attempt to manipulate the jury into believing her reality.
She believes she is powerful enough, superior enough, smart enough to make the evidence fit her story. She is arrogant enough to believe she can con 18 people into believing Juan is a fool and the State's case is as inconsequential as swatting a gnat; that she was a meek and mild, virginal, easily dominated abuse victim incapable of getting away from a man who did vile, reprehensible things; that she is SO good, so thoughtful and considerate she only didn't tell the truth to save those that loved this man any more pain.
If one needs proof Ms. Arias knows her reality isn't THE reality one needs only to look at the letters purportedly written by Travis Alexander, widely reported as forgeries, which coincidentally back up much of her testimony. The letters that surfaced in 2010. Then look to the magazine evidence of witness tampering.
I'd say there is more than enough evidence to conclude Jodi is twisting and manipulating every known fact in this case attempting to make it fit within her version of events.
That is wholly inconsistent with someone suffering from delusional psychosis.
