KIlling children in Roman era movies

[jkaler48]

Both Centurion and the Eagle featured the on screen killing of a child.
Gladiator showed the General's small son's feet twisting in the wind.
The Rome series did show the body of Cleopatra's brother but not the act and it was a necessary historical element of the story.

So is on screen child killing now a requirement for Roman era movies? Will a new Sparticus
movie feature 11 year old gladiators fighting to the death or revolting slaves killing the master's kids?

I object when it is not a necessary historical element of the story.
