has anyone thought about the genetic amplification effect? simply, if there is poison in an enviroment,it will be more apparent twenty generations later, even if most of the origional poison is gone. now, look at it this way: most people grew up well because theirparents were kind, but very hard-assed when needed. now, people bring up their kids and say that they refuse to hit them, or hit them for no reason. so, there is either the effect where people grow up liking the kinder side of their parents, and pass this on through the generations untill there is no discipline, or parents constantly beat the **** out of their kids untill the kid only understands violence. beyond that, movies/ games can only educate people on how to use weapons, or give them ideas as to how to be cruel. I used to play alot of shooters, like socom and cs, and I will tell you that the forces will train you things that these games can describe. most gamers can tell you where the safety is, they can tell you how to change firing rates, they can tell you where the magazine eject is, they can tell you how to maximize accuracy with a given weapon, and can even tell you about some of the basic tactics used by the forces. they will also tell you how to kill a person with a pool stick {hitman}, how to dis-embowel someone with a knife while running {stargate had something like this, and I'm certain hannibal the cannibal did}.
games and movies are just education for things these people already want to do. the most simple example, requiring no thought, is that people get the idea that "oh, I could do this for a living!", and then join the forces. I know six guys who joined because they played alot of games. I have only ever asked eight people why they joined.
