This is a case study in "Normalization of Deviance", a very real psychological phenomenon in any activity requiring risk based decision making. It affects the smart and stupid, competent and incompetent. It was present in decision making leading to the Challenger disaster, and I think here as well.
Essentially, through previous positive experiences "pushing the envelope", we become less and less capable of making proper risk assessments. Our standards become lower and lower, until we receive a corrective experience courtesy of reality. Hopefully the corrective experience isn't a fatal one. In this case it was. However, I think we gain greater benefit to our own decision making process by attempting to understand how such decisions were made, rather than just attributing them to a "murderous idiot".
And don't forget Murphy.
