So, to prevent them from behaving like that, we should avoid such games and fight against them (wow, I sound like a mother goose:D). However, there are games that can even be beneficial for a child. And it's not just those "learn the alphabet with us" type of games. Even "Sid Meier's Pirates" is quite educational in terms of 17th-century history and more. It's great when developers can combine educational and entertaining aspects. Although, it's quite challenging. Another example is "Rome: Total War," also a war game, also with deaths, but at least people don't engage in bestiality. Plus, it features the history of ancient Europe.
