Good pilots live by a Bushido. Ask any aviator whose been around long enough and you'll hear similar tales about their code. If I can't miss it, I drive or take the airlines. I just listen to my gut. These are all examples of a pilot's code of conduct.
All pilots are to some degree.
The difference is that pilots, with a defined Bushido, are more likely to resist the temptation of these unsafe impulses. This code of conduct makes it easier for them to make safer decisions. That's my decision and it's final. Despite the frustration of his associates, his Bushido forbade him to fly in such weather. No further justification was necessary.
