I to would follow the RA in most circumstances and definitely in a situation as the one you describe. But if met with a situation like the one I described earlier, and if in possession of full SA on the only traffic within miles, I would use common sense and be an effective pilot.
No, you wouldn't be. You'd have been wilfully negligent and deliberately endangered your pax, crew and a/c.
In the US , and almost all global FIRs, you are required to follow all TCAS RA's. End of.
