Mindfang is Aranea twisted and bittered by a world that tells her to take what she wants, instead of considering the other person. At least, that'd how I'd see it. And yeah, Sufferer is Kankri when he actually has Social Justice to perpetrate.
Remember, we learned about Mindfang through her diary, and it has always been a possibility that there were embellishments in the delivery. It's most likely that all the things she said happen did, in fact, happen, but I think that, in reality, her personality was more like Aranea's than the diary might imply. It's one thing to SAY you'd chop your own arm off to shut someone like Darkleer up and quite another to actually do so, particularly if you have a glamorized view of yourself.
