Alright. So we're playing Black Crusade, and my players have successfully player-killed themselves into a corner, and are in the service of a Chaos Marine. They have gotten to the point where the Chaos Marine no longer refers to them by name, but by "Minion". they don't even try to improve their lot, they just keep killing each other, while their master, (and i do mean master, they are clearly simpering minions and make no attmept to hide it) watches gleefully.
Not only do they make no attempt to save themselves, they blame me for painting themselves into a corner and accuse me of intentionally screwing them over.
So my question is: have I done something wrong, or are they being irrational? This is my first Black Crusade game that I am GM-ing.
