Yes, it was broken, but by someone else, not me. I am not at (moral) fault for someone else breaking the contract. But if I pull the lever (or pushed a fat man onto the track that would halt the train), I am the one who is responsible for the resulting death, which makes me the one who broke the contract. That's the major dilemma here, because pulling the lever is the utilitarian-correct choice that saved more lives, but whoever pulled the lever went from being innocent to being a murderer.
