because it's not part of the game. why in the hell would you want to kill children anyway? are you sick or something?
I don't want to kill kids. I want kids to be able to die from stray bullets. It's completely different.
And killing kids were apart of 1 and 2. They are apart of the franchise, just because Zenimax decided to take it out after they bought the franchise doesn't mean it never happened and should be ignored.
