hmmm... when I read the title I thought it was going to be some morality issue thing lol. My response was going to be :Nopw, take halo for example. Once your a flood, your pretty much F***** and anybody with good sense probably wouldnt mind getting killed at that point.
OkOkOk real answer: no. Like the military which I know so many who proudly serve, I think targeting should keep a human shape as its only protocol. For instance: When my cousin is in a fire fight in the middle east, and is told to give suppressing fire, he isnt aiming for an individual person, but rather an area. In an FPS, you could think of it like this: its about knowing how big that area is and aiming accordingly.
