I think this guy's only "plan" was martyrdom. He was a deranged idiot who wanted to get killed and have a lot of other idiots think he was a "good guy." This was, basically, suicide-by-obnoxiousness.
Missionaries killed almost all of this tribe with diseases -- they have no immunity because they've never been exposed to anything -- so now they view missionaries as devils. This fool wouldn't take no for an answer, insisted on going somewhere he's clearly not wanted (like our resident troll... too bad Darwin doesn't work for that piece of shit), and he got put down.
Christians are claiming he did it out of "love" for the tribe, but that's absolute horseshit. There's no "love for them," just a fanatical need for the admiration of the rest of his cult. He was selfishly and disrespectfully willing to risk the lives of the entire tribe by exposing them to diseases all so he could tell them his sillyass fairytales which absolutely nobody needs... and how'd this fool think he was gonna do that, anyway? This tribe has been in almost uninterrupted isolation for around 60,000 years. Nobody speaks their language. What's he gonna do, pantomime the whole story of Christ? Which honestly doesn't make a whole lot of sense even if you speak perfect English.
"Yeah, there's this God guy, and he really likes people, but they do bad things. He wants to forgive them, but to do so he has to send down his son (which is actually himself) and have them torture him to death (but not really because he doesn't actually die)... and so then, after all this cruel bloody horror, he can express his love and forgive them. Yeah, I know, you and I would be considered psychopaths if we said, 'Sure, I'll forgive you, but first I have to torture a puppy to death.' But God is different because he's greater than us, see? So the whole bloody torture-murder thing as an expression of love makes perfect sense, and that's why the symbol of our love-religion is a murder weapon/torture device. Huh? Oh, you want to know why were people bad in the first place? Well, see, they had no knowledge of good and evil, so God, he left this forbidden thing in their reach and told them not to touch it, kind of like leaving a knife on the floor where a toddler's crawling. But, not having knowledge of good and evil, they were lured into eating the fruit off the forbidden tree -- by a talking snake -- which gave them knowledge of good and evil and, thus, showed them that they were bad for having done it. That snake who helped them get that knowledge is the real asshole in the story, rather than the guy who left the dangerous thing in the reach of people who were, essentially, infants. Anyway, it doesn't have to make sense, just believe it and after you die you get rewarded. So, life is bad, dying is good. Devalue your life, that's the way to happiness! Slavery is freedom. And, oh yeah, trickle-down economics totally works out great, so if you want to get rich, you should pay more so the people who already have too much get to keep more. See? Now you're being logical!"
I mean, he's gonna convey all that hogwashy horseshit to these people with, what, sock puppets or something? Completely reasonable, his entire plan. He brought a Bible with him, too. They don't even have a concept of written language, but I guess he was gonna teach them to read it? I work with devout Southern Baptists who honestly can't sound out half the stuff in that book. They just follow it 'cuz their daddy did.
What a numbfuck, seriously. That anybody wants to make a "hero" of this guy or pretend he was doing something "nice" is ridiculous. He was a pest, he got squashed, good.
