A: Not enough information, even about easily observable characteristics which may make it a morally hazy conundrum: how old are they, are any of them friends or family? I'm forced to treat their lives as equivalent and so I divert the train
2. Should I push a fat man to save 5 people?
A: No, because I have no guarantee or even belief that pushing him in front of the train is enough to stop it.
3. Should I push a fat saboteur to save 5 people?
A: He sabotaged the train with the express intent to kill 5 people, so risking his life to attempt to mitigate the damage of his action seems like a fitting punishment for the crime. Over he goes.
4. Would I torture him to save a million people?
Oh look, pushing him in front of the train was indeed not a guaranteed success. I wouldn't torture him because I have no belief that doing so would yield timely or accurate information, and because I believe that living in a world where torture is tolerated for any reason truly is a net reduction to sum total happiness, even if preserving that comes with the risk of a million lives.
Score: 100% consistent.
