 We are concerned then with a contrast between two ways the behavior of agents is causally relevant to upshots. One suggestion is to say that when the agent is positively relevant to the upshot, the upshot would not have occurred if the agent had never existed. Suppose, for example, the victim dies because I push his head under water. He wouldn’t have died if I had never existed. On the other hand, suppose he is in deep water and cannot swim and I don’t save him. He would have drowned anyway if I had never existed. In these two cases, the counterfactual account draws the line in the intuitively correct way.
