Can they maintain the appearance of a strict hierarchal chain of command and zealous worship of the God Emperor, things none of them has ever experienced which go utterly against their own ways of living? Would the "Chapter Master" even be able to command their "subordinants" or would everyone just do their own thing?
I'm not sure if they would be able to keep character during burning of heretics/xenos, but I'm pretty sure that they would have no problem keeping the strict chain of command and zealous worship of the God-Emperor.
I mean, the Culture does
have roleplayers; this is just an extremely scaled up LARP.
