In the 2018 movie Suspiria, we see that Mother Suspiriorum kills everyone in the school at the end. Aren't the witches in the school worshiping the three mothers? If that where the case, what is Mother Suspiriorum enraged about? Why does she kill her own worshipers?
She killed them because they were loyal to Marko only (I wrote Mergo because of Bloodborne ahah). Hence, during the film there is a scene where there is a sort of vote, and the majority vote for Marko, making Mother Suspiriorum lose. In brief, Suspiriorum killed those who were not loyal to her, but to Marko.
