Also let's not forget, that Chaos is chaotic... Infighting is quite common on their side.
Exactly. I seem to recall the Planescape faction the Xaositects randomly fighting with/for and
against members of their own faction.
"The trick for a Xaosman, of course, is to become at one with the disorder of the multiverse. One cannot try too hard to be random and disordered, because that's not chaos. Neither is chaos always random... sometimes a Xaosman will just show up and start speaking normal, just to confuse you. The best Xaositects seem to have a knack for knowing exactly what you expect of them... and then doing something else.
This would seem to hold true for all Agents of Chaos, so your party members could feasibly attack, kill and loot other chaotics.
