It would be difficult to make that work in the context of the game. ME is not Uncharted with a clealy defined protagonist character. they want you to be the main character and tell him how to feel about situations. And having Shepard be emotional without the players input would break the illusion, make it seem like the game is telling you how to feel in that moment
