If your not actually going out and putting into practice the fantasies you're playing out in your video games then it's not really a problem is it
they are video games characters after all, pixels
Remember these things don't translate into reality that's the core concept of a video game they are just games, just for fun like any of types of digital entertainment
and for those few individuals that do practice the things the see on TV or read in books or play in video games, those individuals typically have an underlining instability. It's good when a piece of art can move a person to question the philosophies of life it shows a lot of creative thinking, a lot of imagination as long as your not just spinning your wheels, racking your brains on a issues that's not really an issue than actually tackling the issues of the day. Remember television and video game violence doesn't translate to real world violence, in fact it's the opposite. Pornography didn't increase the frequency of sexually deviant it's reduced it. So on the head, don't worry about it, there fantasies, nonsense. You should start to worry only if you walk past a turtle in the zoo and your fist consideration is to ump on it and use it's shell to knock out the rest of the patreons- hmm maybe that's why I can't go to the pet store any longer...
