Another example would be Ben's fate.
Letting him fall to his death in the bell tower was very satisfying to someone I know who despised Ben and had wanted him dead since Ep. 3.
But seeing him and Kenny make up and go out together was very satisfying to me who had tried to keep the group together the whole time.
So just because Ben dies regardless doesn't mean that every choice pertaining to his character was pointless, they change the way you experience the story and the emotions you feel as you play.
