I would pull the lever in the trolley problem and don't support murdering people for organs.
The reason is that murdering people for organs has massive second-order effects: public fear, the desire to avoid medical care if harvesting is done in those contexts, disproportionate targeting of the organ harvesting onto the least fortunate, etc.
The fact that forcibly harvesting someone’s organs against their will did not make your list is rather worrying. Most people would have moral hangups around that aspect.
