The clips are pretty violent but I don't have an issue with it. In both cases the violence seems to be part of the story rather than for the sake of it. And the actual messages are pretty positive. The character in the first clip being saved for intervening and stopping further violence against that other character, and the robot in the 2nd clip stopping the dad using violence against his child. So the games seem to be using violence as a device rather than promoting it.
On the issue of ratings and kids, I don't actually think violence in video games causes real life violence or influences kids to become violent, even kids know the difference between reality and a video game, they're not given enough credit sometimes. And if the violence frightens them so that they wouldn't enjoy the game, then they won't want to play it. I just don't think it's that much of an issue.
