Essentially, they see the humans amongst the group as being misguided, because they come from planets that The Emperors holy light hasn't touched. So, they plan to introduce the other humans to the cult and put their heads on straight, I mean, you can't blame people for not worshipping his holy might when they have never heard of him, after all, When His Holiness first touched down on Fenris, nobody there had heard of him, same with Macragge.
