Desire: fame, sex, money, power, revenge, lust, greed, envy, jealousy, ambition
Anger: (a given, according to these FBI agents)
Guilt: regret, shame, remorse
Then the psychological profiler, Lien-hua, (who is all about determining motive), says that she thinks there are two additional--more important--motives that Patrick missed. She reveals the first one:
Fear. She says fear can turn you into a different person and make you do things you'd never do when you're pushed into a corner.
Patrick spends a lot of the novel trying to determine the fifth. I found myself highlighting all their interactions regarding this illusive fifth motive.
He guesses survival, to which Lien-hua responds is the desire to live. Then he tries betrayal. Lien-hua says that you betray someone because of desire, and you respond to betrayal with anger. Patrick's next guess is curiosity. Lien-hua says that curiosity is desire to know what the crime will feel like or how it will affect you. Patrick then guesses psychosis and depression, both of which Lien-hua say are conditions, now motivations. They might precipitate or increase the likelihood of certain behaviors, but they don't motivate the actual behavior.
Patrick then internally dismisses the idea of honor and vanity as forms of desire. He likewise dismisses duty as the desire to please and integrity as the desire to be virtuous. He next guesses remorse, to which Lien-hua responds, "That's just another name for guilt."
He never does manager to guess it correctly and Lien-hua ends up telling him. It rocks his little FBI world. but before I go further....
...can YOU guess the fifth motive?
Be sure to check back at the end of the day. If no one guesses Motive #5 correctly, I'll post the answer around 6 p.m. PST (9 p.m. EST).
