To me, all that is relevant here, is the safety of the travelling public, who are obliged to place their trust in whatever FD crew are flying the plane on that particular day. And assume that the airlines, regulators, or whoever, are doing whatever it takes to ensure that this trust is well placed. That the crew are healthy in every particular, and on top of their game for whatever hazard they might have to face.
If a pilot loses his license for any medical, conduct, mental problem, then so be it. It is a risk they accept when signing up, as is the case in many other professions.
And I doubt that any of the friends and relations of the dead 150 or so would say different.
