Would be interesting to see if when one agent declines to help another several times, the other one would decide against helping him when he calls. The logical explanation would then be that the agent would come to value his life more than his comrade's (because he is helping, and his comrade has refused several times). The human explanation would be that he refuses to help out of spite. It could even lead to those two agents "hating" the other, though it would be more like cold calculation.
