"spare the rod, spoil the child"
Things may have been a bit strict back in the day, but you can be sure that behaviour like that would not have been tolerated.
On a side note, I'm not against violent games... hell, I love them. But some of today's point and shoot games seem so mindless at times

... Is it any wonder that they contibute to kids such as that one?
.... and again, let me stress, I have no problems with violence in games, but the mindlesness of some of them makes me sick
