Fanatics are always bad news, no matter if it's for light or darkness.

Even Al Tharmen believe they are doing what's best for mankind. They think by turning all Humans to the black rukh, they can break everyone out of a pre-destined destiny and thus mankind can gain true freedom.

But that makes them all the more dangerous and scary. They are so convinced that they are doing the right thing, that they will stop at absolutely nothing, including self-sacrifice, to achieve their ultimate goal.

Just like Magomet was willing to sacrifice his body and soul to protect his "children", never realizing the harm he was doing to the ones he tried to protect, until Aladdin and Titus managed to get him to his senses. Only that unlike Magomet, Al Tharmen know exactly what they do and how much "collateral damage" they are causing, so talking them into quitting is next to impossible.
