Give him a break, the guy is in Iraq. Part of the psychology of warfare is to attribute peoples deaths to mistakes on their part. Its what psychologists call "The world is fair" hypothesis.
For example, if a normal, everyday person is killed in a car crash for no reason, it makes you feel bad. On a deeper level, it shows that you can easily be killed too. However, if you can attribute a mistake to them, such as they were adjusting the radio, you can start to feel superior to them. "Well that person died because he wasn't very smart, and I am much smarter than him, so I will be ok". Of course you don't think about this on a conscious level usually. Its really just some fleeting thoughts that come together to give you a feeling about it.
