I have watched the movie several times. I have read the book 2 times. Mc Donald is an obvious sociopath. His behavior throughout the entire film is consistent with the actions of a sociopath. The physical evidence presented at trial clearly pointed to his guilt. The blood testimony in itself painted a pretty tough nut to crack. This case and the Scott Peterson case prove that a sociopath does what he has to do to protect his or hers way of life. Logic may or may not apply. Mc Donald had affairs. He obviously wasn't overly comfortable with his lifestyle. As with Peterson, he was deeply involved with other women. That is motive enough for a sociopath. Their wants trump anything anyone else would want or need. Murder is not a moral decision for a sociopath. It is a means to achieve an end. The issue of conscience doesn't exist for a sociopath. So judging Mc Donald using conventional logic just is not a good fit. To people of conscience, how could Mc Donald murder his wife and children? However, to a sociopath it is just a ways to a mean. Don't be fooled by Mc Donald's line of bull. This is what a sociopath is good at.
