Imagine we found a way to un-temper people. How many people whos loved ones we killed because they were "irredeemable" would be VERY mad at us?
We are this worlds equivalent of a WMD, and a figure of high influence at this point in the story. Everyone wants us in their thrall and, as in the real world, some would just want us out of the picture entirely if they cannot have us on their side.
I don't think this is an entirely impossible thread, and it'd be a change of pace not to be the paragon for a while.
