In my example I very clearly am rallying against Alice. In every possible way. I would be fuming, throwing stones, screaming to everyone around me. But I would not accept her proposition to Bob. I would not claim that I "have" to play Alice's game, because she's in charge and I have to accept that. I don't have to accept that. At all.
I would do everything I could to stop her, and almost all of my Anger would be towards her, not towards Bob (I obviously would be angry with him too but he's after all not a murderer - Alice is).
Keep in mind that in the example, Bob probably believes for some reason that when Alice says two, she means ten.
In this scenario, I'm not the one choosing, Bob is. And when Bob says "five", i will be angry, but it will be nothing in comparison with my Anger towards Alice who now can kill five people instead of the two she has been killing on a regular basis before. She's the one presenting the alternatives, Bob isn't. She's the one performing the murders, Bob isn't. She's the one that deserves my anger.
In a similar fashion I am not angry with anyone saying "two" either, "beacuse they could've said none yadayada". I am, almost exclusively, angry with Alice.
