Nobody panics when things go “according to plan.” Even if the plan is horrifying! If, tomorrow, I tell the press that, like, an aid worker will get shot, or a truckload of humanitarians will be blown up, nobody panics, because it’s all “part of the plan”. But when I say that one little old CEO will die, well then everyone loses their minds!
That the Xanatos gambit is what I now expect from all good villains. Any villain worth their salt has a way to defeat the hero — even captured, killed, or frustrated.
