Oh, I definately agree with you there because, I'll admit, I'm personally quick to say 'no they do not' ..but the subject, like any other, needs a controlled study to give us any real info.
If hard evidence
was presented, then... hell, I dont know. What would they do, ban all the movies, books, games; past, present and future? Only allow a certain type of violence?
I lean towards violence as being part of the first law of nature, self-preservation, and when people lash out it's because they feel pushed beyond a threshold they know how to deal with. Whether it works this way for someone truly deranged, I dont know - I mean, crazy is just plain crazy
..but for someone who is, for all intents and purposes, an average individual, I think the former applies.
Can violent images turn a normal being into a killer bent on murder? I find it hard to believe.
However, the undeveloped mind of a child is another thing entirely - they may just be able to be taught violence is okay, a way to solve their problems. Even then I'm not sure only because of interviews I've seen with children in parts of Africa who from an early age are thrown into violent realities, given guns, forced to kill their friends, family - even they, after being removed from those situations, they say it was all wrong and that they didnt feel right about it at all. Now there is good evidence that even a violent
reality doesnt change a person, or child, into a murderer.
