It's always enlightening to be provided with some previously unknown fact that condones an action and then having the accusation made that i would take the moral high ground when faced with the very same situation when no further details are provided.
First of all I am not privy to these details so cannot comment on whether the person in question could wait and go public or had to go private or even the seriousness of the situation.
However I would suggest that at the very least the person in question could explain themselves to the NZ pilot group as to why they decided to "systematically" undermine the NZ pilot group cause.
The other Aus based pilots on days off in a NZ hotel also went to great lengths to collect the money on their days off at the expense of the NZ pilots Did they also have $75k expenses or did they simply want to buy a new car.
There are products generally known as private health insurance available and 8k is only 10% of the medical bill, hopefully it was worth it.
"Does the end justify the means"?
I don't know Framer, perhaps you can explain?
