Frankly I like it. I generally don't like torture scenes, but this does seem to kind of fit with her MO (and the flames may or may not be influencing her personality) so it makes sense. I don't think going any farther would help her cause any, and if you wanted a specific reason you could have tattletale mention in a later chapter that she talked her down from a bigger display. Anyways, a certain amount of torture benefits her cause, but too much could cause repercussions from the public and PRT as well.
Keep on keeping on! I'm looking forwards to more!
