If you are versed in psychology, this is a great textbook example.
From the beginning of this series, right to the very end this person displays dissociative characteristics of Narcissism.
If you pay very close attention to the word selection chosen by Barry Minkow in the last few scenes, you will see what I am talking about.
For example, when talking of the damage he has done to peoples lives, it is "Total" and massive, when he is talking about the homeless, he talks of doing "ten times more" evil than they have.
Notice the extreme, grandiose nature of the language. It is not small.
It really shows you why anyone who has dealt with narcisssists in their lives will tell you to run a mile.
Nearly totally resistant to any form of treatment (Ie. Nearly incapable of true reformation), yet like a chameleon, able to learn and act out all the behaviours they feel are required.
No empathy for others, treated as things, or pawns in a game where the outcome (their glory) is important.
A cautionary tale.
If you have any narcissists in your life, RUN A MILE.
