Thing,
I think that makes sense pretty much. The operative point, in regard to PDE, is what you are intending to do. Although you said that you are choosing the fat man, you don’t mean (really) that you intend to hit him. You are intending to divert the trolley away from the 5 people, and you accept that it is going to hit the fat man. But, if the fat man got off that track. . . GREAT. You would be happy with that outcome. And you would still choose that track.
As far as making either choice without blame, perhaps you are right if you mean no one would hold you accountable for such a stressful spur of the moment decision no matter what you chose. But, if we abstract from the stress of the moment, I’m not sure the choices are, in themselves, equal. We can see that choosing to switch the trolley to track B isn’t necessarily a morally bad choice. But, I’m not sure that we can say that leaving it on track A is just as good a choice as switching it. If you are weighing the consequences of your choices, it would seem that switching to track B has less evil consequences than letting it ride on track A.
This all applies to the first scenario only though. The second scenario is a different thing.
