I was more getting at "your actions will have more consequence".
In Oblivion, innocent NPC has good loot so you kill him and that's the end of it. No one reacts to his death, there are no pieces to pick up, the world goes on. If, as we're told is the case in Skyrim, NPCs are now integrated into cohesive family units, then the murder of said NPC would bear some weight and effect in the game world. The family would react, they may mourn, their house may have an empty seat. The abstraction of "it's just a game character" is mixed with emotion. I will see the consequences, I will see the trauma. For me, it would make me feel more guilty than if the NPC just died, leaving no evidence and no witness. More emotion is what I'm saying, seeing something or someone in pain. The townsfolk remarking on what I've done with disdain.
For example, if I slayed a bandit... and then his friend dropped to his knees in shock, dispair. Rather than his friend paying no heed, like the artifical intelligence he is.
But I digress entirely from the subject of children.
I really doubt such a thing will be in game, I'm certain it would effect the games rating.
Killing with no significant emotional consequence isn't relealistic or relatable and therefore is generally ok in games and films.
So while there may be some shallow anger, I doubt there will be traumatised kids running about the place.
