In that case, I would kill the queen in your evil hive and swap a frame or two of very young brood and eggs in from one of your gentlest hives. If you give the hot hive very few options for creating a queen (they need eggs or a 3 day old larva for the best queen), then they will use the donated frames to make a new queen. Wipe out any queen cells on other frames at about 5 day intervals to prevent a resurrection of the devil queen bee.
Just my thoughts. I bet @JeffH has some good ideas too.
All of this assumes that the super-hot hive has plenty of food stores, and no other threats or issues (like ants, toads, predators etc).
