It´s all in how kids are being raised. I pretty much see it this way:
A child is born, and he or she is blank! So that little person must now learn everything from the beginning, and will do so. That is, will learn what the teacher (the parents) teaches! Get it?
They do what the parents make them do! They don´t know any better. They are so receptive, that they copy everything that the parents do, are, say. Down to the last little detail. That includes the bad deeds too. So if any parent has a problem with the behaviour of their child/children, they had better look at themselves and make the appropriate changes there first before complaining! Next there is the huge problem of secondary influence from the surrounding society! Rap musicians who sing lyrics about raping, killing etc. Tv shows where people participate to be seen and to view other people fight open, brute battles (whether it be verbal or physical), with no intimate details left out and walk home craving more. School kids who "persuade" them to follow the latest trends, and which doesn´t stop short of the most violent games, movies if they are deemed cool by a leader of the pack. The blind follow the blind, and the rich get richer on other peoples moral and intellectual ruin. I see it over here and I see it elsewhere in the world. You gotta admit it to yourself: the world is going down, and it is not going to get better until it has gotten a lot worse. Have we even hit the bottom yet? Are people strong enough to steer cleer of the pitfalls which can dangerously alter their behaviour, and provenly so?
Parental responsibility, if not strictly enforced, will eventually result in a generation of children who grow up being insensitive to too many things. Including killings, theft, rape etc. I am not saying they will all develope into homicidal maniacs, but the foundation has been laid already. Some of them, if not many of them, will. The seeds are in the ground, and they are sprouting everywhere. Who knows what people do outside the media-spotlight? What they get away with, without ever being brought to justice for lack of evidence? This everyday incident or that international conflict, this invasion or that invasion which trigger something inside them which has been steadily built up over the years playing games the others said were harmless, being exposed to violent or downright stupid media output again and again, eroding the boundaries of the sense of morale, sense of reason? So a lot could be going on already, which we don´t hear about and which is rooted in a society marred by media-created violence, gore and which appeals to only the lowest instincts in the human psyche. Drugs are everywhere too adding to the probable dangers with their mindaltering abilities. I personally know of people who are exactly like in the above scenario and I do my best to stay very far away from them.
Best hope that there will eventually arise a new trend in society, one which has zero tolerance towards irresponsibility on the administrative levels of society, and towards greedy executives in the media who value the Mighty Buck higher than they do human relations. Perhaps when people overall get enough of shootings (which is really only the tip of the iceberg, signalling grave disorders in childrearing these days) they will start to unite and do something on a worldwide scale. Of course, that would have to be controlled from a high level of political office.
The alternative, I am afraid, will be generations of people who don´t care about anything, resulting in anything from local crime incidents popping up everywhere on a steady rate to wholesale obliteration worldwide. There is already wars everywhere, all the time threatening to spill over to other regions and becoming a major worldwide conflict and the only thing that can stop it, is people who love their fellow man and woman and child and who will be seen by people as beacons of light in the evergrowing darkness, so that they will be listened to and followed. Even if not expressed directly, then in the heart and in the mind. People need such leaders, who will make them see the right way to conduct themselves. Rear their kids etc. Preach over.
Society is made by people, and the quality of people in said society directly determines the quality of that society. No kidding! And remember that those who are children/adolescents now, will be tomorrows adults! But what adults will they be? And where will they work, and what power will they wield? How well will they be able to conceal their probable psychopathic tendencies and will there be enough people with a proper morale to keep them out of the picture altogether seeing the danger before it becomes an unavoidable threat? You don´t want a guy who has gone cold, blank, dead inside, to sit with the finger on the nuclear trigger, would you? I have seen all of above things for years, and I am not exaggerating. Now it´s come so far that it hits the news several times weekly in newspapers all over the world. Ominious signs.
