I think the value of making these mistakes is in learning from them and then making sure they can't happen again. Leaving this process in place and just making this guy run the command forever because he screwed it up once would be a much less effective solution than fixing the tooling so it's impossible to do this in the first place. Saying "this guy don't do it again" also offers absolution to everyone else on the team. In a healthy culture only we can fail.
