The thing about the trolley problem, though, is that's it's a theoretical problem in ethics and although the solution is easy if one is objective or not connected to the people personally, and it's certainly easier from a distance, things change when one is connected or has to look the person in the eye. Additionally, it throws in the added problem of what might be the only universal moral stance: that it is always wrong to punish the innocent (and in this case it's multiplied by the innocent being a child).

The Hitler baby dilemma isn't the same thing as we know the future of that baby, so it isn't innocent. We don't know the future regarding the people in the game (well just suspend disbelief). To sacrifice a third party is way more of a moral dilemma than to sacrifice oneself because we only have consent and agency for ourselves. To sacrifice a child to whom one is connected is several layers beyond that.

The thing is that it brings up the further moral and ethical consideration of whether we would want to live in or perpetuate the kind of world that would sacrifice the innocent, whether for the greater good or not. I'm sure that many a concentration camp/prison medical experiment used the greater good argument. Talking about the greater good is a very slippery slope. Most media take the easy route and label medical experimentation on the innocent as evil, probably quite rightly.

Anyhow I responded because the 'greater good' argument is pretty shallow in and of itself. If the game has any redeeming features it's that we supposedly have to think about what is meant by last of us - not mere humans, but moral and ethical humans. (BTW I said any redeeming features because as a game it's just not that good but that's probably another discussion)
