I agree with you
But I also believe that just because you are born with a propensity for violence that you will be violent.
I believe that a nurturing family that disciplines a child that displays violence and cruelty and rewards kindness can prevent that propensity for violence from being developed.
The violent video games, death metal music and gangster rap I believe simply reinforce the violent behavior by normalizing the feelings they have for anger, hatred and cruelty.
like i said,the video games,music,etc. has nothing to do with it. but i will agree on the nurturing.good point.if a parent sees something wrong,they should take action and try to curb it as best as they can.but ,you can't be with them 24/7.right?
