I would not pay $600k to teach everyone at the company that if they make a mistake I will fire them to set an example. If that was my position, it's a lot cheaper just to walk around threatening people and making them feel paranoid every day at work. But I think it's a bad position to take. So I'd probably keep the one guy who is never going to make that mistake again around, and fix whatever system allowed the mistake to happen in the first place.
