The character Kevin Lomax's name may be a reference to being a "Low MACH." This is a term used to describe those people scoring below 60/100 on the MACH-IV test used by personality and social psychologists to measure "Machiavellianism" which is a measure of a person's tendency to manipulate and deceive others for personal gain. E.g. "Low MACHs" tend to agree with the following statements (taken from the test): No. 7.) "There is no excuse for lying to someone else." No. 11.) "Most people who get ahead in the world lead clean, moral lives." These are precisely some of the personal moral issues faced by the character in the film.
