What is wrong with People these days?

What is wrong with people these days? There have been so many killings. People going into schools and shooting innocent children. Lately I've read more and more cases of child abuse - physical in nature where the child has died. These are little kids, that did nothing wrong.
Senators behaving in ways that are not appropriate. Every where you look these days, someone is doing something they shouldn't be.

In some of the cases, these poeple had been abused when they were younger or had abused others. They kept those secrets and eventually that anger had to go somewhere. Instead of getting themselves professional help, they have taken it out on others. Others, that had nothing to do with their pain and suffering.
With all the awareness of sexual abuse these days, anyone who has been abused should seek help once they know or suspect it has happened to them. It no longer has to be kept a secret. Every one has a choice to make. They can either become an abuser themselves or they can get help and stop the cycle. The strong ones, stop the cycle.
For the guy who killed the Amish girls, who struggled with the death of his infant daughter and who also was having dreams of abusing children again, it would have shown strength on his part to go and get help. Instead, he took it out on those who had nothing to do with his pain. The only good that came of it, was he killed himself.
And what about the kids who go into the schools and kill other kids. They have habored anger, a lot of the times because they have been bullied. These kids are depressed and even if they are being treated, no one is taking notice as to how they are doing or what they are doing. If they had more parental guidance and parents paid more attention to where their kids went on the internet, things may be different.
There will always be killings, kidnappings and rapes but, it just seems to keep getting worse not matter what is done to try and stop it.

How do we (as a country), get all these people to understand that violence does not solve anything?
