There is one: (1) let Stallman keep his position and inspire/encourage one set of people, while discouraging/putting off another; (2) remove Stallman from his position, foregoing both the inspiration/encouragement and the discouragement/putting off.
That wasn't really the question, though. There was nothing there about saving lives _by_ murdering someone. It's more like "is it ok do do bad things if you've built up good karma beforehand by doing more good stuff".
It is not the Trolley Problem because the literal question is "Is it okay for someone to murder a person if they saved more than one life before?" and that is not the Trolley Problem, that is the "letting someone off the hook for present and future misdeeds based on past good acts."
