The paths that lead to jobs in aviation, and those that lead to engineering your own public freak-out on your way to 7.5 minutes of fame are mutually exclusive.
Giving that guy his job back would be a slap in the face to every professional flight attendant in the industry: those that manage to handle actual conflicts gracefully. And it would be a big "high-five" to every unprofessional flight attendant, those that create conflicts where they don't exist. The people that are unwittingly coming to his rescue are doing it because they think his behavior is a symptom of the problems of air travel. On closer examination, he is one of the problems of air travel.
As a separate note, I was talking just yesterday with the Captain about the way the FAA treated the pilots of NW188. What an insult it would be to those guys, professional people that made one error along a good career, but happened to get caught in the middle of a FAA/media lynch mob, to see this guy return to work.
He misplanned his blaze of glory, and he's getting burned. So be it.
