Anon, it's simple. There is a Big Human in the sky, and if you don't worship him, he'll light you on fire, forever. This missionary was simply saving the tribesman from the Big Human's terrible fiery wrath.

Important note: the Big Human omnisciently foresaw the future sins of the tribesmen the moment they were created, but he will still punish them, even though he's the one who made them that way
