I can see a few other classes working well, but none quite as well as the Monk class. Blunt, not caring what people think of them (lol, I'd call that a positive trait), adaptable... The line about seeing a silver lining fits the majority of them perfectly, and the earlier monks have a type of spirituality. They're a lot more forgiving than most other options as a whole, and much of your reasoning in the situational questions fits well.
