Nobody negotiated a deal. Creed foolishly tried to commit Morek to a course of action Busto wasn't willing to pursue, and Malus didn't "offer" anything except religious tolerance. There seriously wasn't a deal. There was a period where PeL was pursuing any savior it could find, and people probably caught the stench of desperation. That doesn't mean Malus was running around slamming doors.
Religious tolerance alone is generally enough to make us delighted, especially when its in an area that had been closed off to us before. You certainly nullified any slim chance there might have been of Morek shifting itself off the couch to potentially intervene.
