Your version adds an irrelevancy - the possible moral agency of the demon provides an out for the test subject: "It is not my fault those 5 people died; the demon did it." It is much more difficult to shift moral responsibility to the trolley.

I'm not sure why it's perceived as more difficult. The trolley didn't just appear magically on the tracks. Someone put it there and set it moving (or negligently allowed it to).
