No question @ why so many USA kids kill clmates & teachers? Satanist heavy metal bands influence how many?

when violence is normalised by an avaricious media hell bent on making money no matter what the cost and computer games that revel in violence pop groups sneering and smashing guitars on stage what do we really expect , Children learn from what is around them which is a natural course for children to do , we have allowed greed and irresponsibility to rule now we are reaping the whirlwind of our own apathy.
