This was always something that bugged me about bad guys in movies & cartoons...a henchman would screw up, so they'd fire or kill them because of their mistake. But I've read several business reports from managers who oversaw huge mistakes and the smart ones never fire the person who did it...there was one story I read where somebody made a $100k mistake, and the manager being interviewed said it'd be stupid to fire that person because that guy now had an extra $100k of experience & would be even better & more careful at his job as a result of making that mistake (obviously, that's barring people who are literally incompetent or don't care), versus having to hire someone new & train them on the process & risk other mistakes after the original mistake had been patched. I think that's a pretty smart approach, especially since there should be controls in place to prevent people from royally screwing things up in the first place, so to blame people for mistakes they didn't intend to make is a bit silly, even when it's a big-ticket item, because that responsibility should really fall on the organization to manage. That's not to say people should be absolved of all responsibility or consequences from their business mistakes, but in this case, the system boiled down to a single point of failure, which was eventually tripped over.
