Mind-altering drugs/mechanics will certainly be an option, and there will be other incentives as well— similar to the Hunger Games, if operators realize that there isn't enough authentic emotion in the situation, they'll find ways to make things dire. Note also, the 'true' inhabitants of Panultima (both primus and servus) will be somewhat brainwashed/indoctrinated into their world, believing this to be all they have ever known, making it hard to hold onto old values and morals. In order to blend in and obtain the necessary information, Thor would know he most likely has to act similarly. Even if part of him doesn't want to.

We'll definitely be sure to talk about this in the plotting post!
