The very fact they'd travelled right the way to Switzerland and he'd talked it through with the missus and there was a documentary being made meant there was ALREADY plenty of coercion in the room.
It would take a very brave man to say 'Actually, cancel the documentary, go buy a plane ticket, changed my mind everyone - oops'.
in fact, face it, it's not going to happen. To all but the strongest human beings, there really would be very little choice at this point. The expectation for a living person is they top themselves.
I never want to live in a society where at ANY point the expectation is you really should be topping yourself ..
