People assuming things doesn't mean there is a pact, explicit or otherwise. Isn't the whole idea of a social contract (which is what you describe, right?) of any kind debatable and really unprovable? Couldn't one say it simply is a responsibility they have collectively taken onto themselves, on their own? Of course, it doesn't change what will happen, what rescuers will do. Probably won't even change how they'll do it, or how they'll express their motivations from doing so. So... how do you prove or disprove the existence of said pact?
