I think trolley problems are mostly linguistic. Take this wording: "Oh no! A trolley is careening into a crowd! Should I try to turn it so it goes through the sparsest part of the crowd?" I think most people — by a wide margin — would say yes, because it's worded as still hitting the same thing, just hitting it in a way that does less damage, and we feel differently about that than hitting a different thing, "this guy" instead of "those guys".
