granted it is sad as to what happened to Louise, but i see her purpose in Gundam more to show the effect of War or conflict on civilians. it shows that even if you are a non-com, no one is safe from the battlefield, and civilians usually are the ones who suffer from someone else's choices. they have been involved in at least maybe wat, 2 or 3 incidents? first with the orbital block, the bus-bombing, and now for louise a random act of violence.
