Was not going to reply until I saw this is actually a month old and not more than three years, so you're in luck.

The Confessor claims to have been a violent criminal, and in Interlude with the Confessor we see the Confessor say this to Akon:

And faster than you imagine possible, people would adjust to that state of affairs. It would no longer sound quite so shocking as it did at first. Babyeater children are dying horrible, agonizing deaths in their parents' stomachs? Deplorable, of course, but things have always been that way. It would no longer be news. It would all be part of the plan."

Contrast with the Joker in Dark Knight:

You know what I noticed? Nobody panics when things go according to plan. Even when the plan is horrifying. If tomorrow I told the press that, like, a gang-banger would get shot, or a truckload of soldiers will be blown up, nobody panics. Because it's all part of the plan. But when I say that one little old mayor will die, well then everybody loses their minds!

One hundred chapters of HPMoR have taught us that Eliezer is totally okay with throwing these references in. I think it's pretty clear (also hilarious, because all of the Joker's plots in Dark Knight were game-theory-esque, tying in with this gigantic Prisoner's Dilemma story).
