Well, not meaning to give spoilers (though this is technically something revealed in a recent book, I guess)...I think they make excellent villains, so lets round up some heroes and take the fight to them!
It would help a lot if the heroes specifically rounded up for fighting them didn't get "compleated" and/or murder other allied heroes. Because that's literally what happened. Ajani Goldmane apparently got compleated off-screen, and killed Jaya Ballard thereafter. So one of the people shown in this image is dead, another has been forcibly corrupted and turned into one of the horrific religio-fascist torture-fetishists, and the third is the leader of the religio-fascist torture-fetishists.
