Horse shit. He was most likely inoculated against all thesuperbugs mankind has encountered heretofore; not to mention your lack of curiosity as to the diseases he might contract from “them”. It’s a bullshit argument barely worthy of comment. But in your case I’ll make an exception...
Perhaps you could provide a list of the jabs he had and another list of the diseases these tribesmen could give him ?
what difference would it make? this island is a unique situation and not some potential tourist spot. this dude knew full well he could get killed doing what he was doing and hey - he was right. score one for him in the end.
if you go play in traffic during rush hour, odds are you're going to get hit. so best advice i have is don't do that. if you go to this island you're going to die, so; don't do that.
we have no idea what havoc we could create by forcing our ways on them. why should we anyway? they are doing fine on their own and seem happy. leave 'em alone and stop trying to force them into world they obviously don't wish to be a part of. there are days i look around and i wish i could find some island and get away from mankind's stupidity.
he was stupid, he died. end of story.
