Any crimes committed by Kellhus after the events in TTT we can assume are done with the greater plan of ridding the world of the Consult and Inchoroi in mind. Not all actions are equal in Earwa. We need Mimara to see Kellhus with the Judging Eye to truly know if Kellhus is objectively holy or insane (being one might mean being the other, too, that won't be so easy to find out).
