I have read, fwiw, that much of this is caused by the violence children watch on t.v. and, also, on their video games.
I know that studies were conducted on that and that was their conclusion.
I grant you studies seem to prove whatever anyone wishes...otoh, I can’t figure out any better reason. Children do become what they are taught and exposed to, that much is a fact.
I’m also certain that the breakdown in the family unit has much to do with this, as well, and, naturally, removal of God and Christian values from just about everything is most likely the main cause of this, as children raised without values will fill up with bad values.
Agree; surely 'family' environment is a big part here. Funny, how little they really disclose about these perps. . .their life stories, really. Their likes/dislikes; interests etc./et al. . .
Think as well, today, Liberalism/PC makes it even harder for young men to 'define' themselves. We are 'growing' students, who are unchallenged. Without real heroes - authentic, real or mythic; without benefit of real competition; and 'scores' while on the playing field; be it organized sports or recess. In their classrooms; they are without 'real grades - and so no honest intellectual competition as well. (Even school Valedictorians are becoming an 'acheivement threat' to another students ego. . .)
In many homes; there is no 'real' Father either. That 'boys will be boys' is no longer tolerated. No rough play; no 'play guns'. . .Their 'real' competition is supplanted by the safe. . .and inauthentic, 'virtual realities'.
Anyway, fewer tests of their 'boyness' - soon to be 'manness'. Fewer challenges; and meantime, the growing wells of testosterone become threatening; particularly, as you say. . .for those children, in less than ideal situations.
These kids are living an 'inauthentic' childhood. At some point; they want and require 'real' tests of who they are; at least beyond the relativity of the 'egalitarian playing field' and beond the challenges - and false confirmations - of a video game.
Think in the end; sadly, the most troubled of these boys, looks for a reality they can actually feel if only by their own violent impact. They confirm the pain of emptiness; of lving a life where no test or challenge has defined in authentic terms; 'who they are' and by turn, 'who they can be'. . .
IMHO, lyrics in many songs are absolutely horrible. I don't understand the need to glorify topics such as suicide, but they do. Do we tell them to quit writing them, ie speech? I don't think so...however there they are, thrown on albums..either randomly, or entirely. It's crazy.
note: Not for the faint of heart
