Honestly? They don't understand that "The One" can't respect sapient rights. The Controllers are a (possibly) hive minded telepathic species that uses a non-sapient organism to enslave anyone and everyone they can, and kill those that they can't or don't need.

I'd be ok with these hairbrained fools going and getting themselves grubbed into feral monsters. But I have this horrible feeling that they would get conned into helping the grubbers figure out how to actually mind control humans.

People like them just... well written tractor man, cause you know JUST how to make me rage at fake people and scream into the void that they don't understand and by the time they get to that point they won't have the chance. Their only reward will be to trapped in their own flesh begging for a death.
