As a person who has been playing games for a large amount of years i have never been tempted to practise any violence outside of the virtual reality.My personal opinion is that it allways comes to a personality.If you are having personal strugles of any kind and you find peace into a brutal and savage game then that means you can have personal issues which might lead to a dangerous thoughts. , temptations and behaviour into the feature. This is the reason why i cannot completely agree with the scientific researches on 100% because they measure the mass and cannot turn their attention to specific cases. Overall amazing and usefull post. Looking forward on reading more! :)
