The Hellfire Club wasn't villains in the traditional, we will take over the world by force sense. They were rich and powerful business people who happened to be mutants and used their wealth and connections to get what they wanted.
I really want to see the Hellfire Club go back to that after this Krakoa thing is over. Shaw as Lord Imperial with 10 other mutants as the white/black chess pieces. As well a whole new Hellions as their mutant operatives.
