High School Students on Long Island Film Stabbing Instead of Helping Victim

A young teenager was bleeding to death, right before their eyes, in a strip mall in Nassau County, Long Island, NY and none of the teenagers surrounding him, tried to help. Most were video taping his  death from stab wounds, with their cell phones to later post on social media.
In a suburban setting, where teens attend a well rated neighborhood high school, an after school fight  broke out over a girl. Khaseen Morris would end up dead. With no one to help him, until the police arrived and then it was too late.
What is so abhorrent about this story is the callousness of those who watched and filmed instead of offering help. Maybe they could have saved him, but it was more important for most of them to film his suffering instead. (Though according to reports, some at least called 911 for help.)
An 18-year-old has been charged in his death. UPDATE: And most recently seven others have been charged in the senseless death of this young man.
According to Detective Lt. Stephen Fitzpatrick of the Nassau County Police Department, "Kids stood there and didn't help Khassen. They videod his death instead of helping him." Sickening.
And so you have to wonder, if you take all conversation and discussion of God and religion and religious values out of public schools and not replace it with some kind of character building education/lessons, then what you get is some teens who lack common decency and compassion for their fellow human being.
There is no reason why religious/spiritual truths from the major world religions cannot be taught in public schools, without proselytizing. Or give lessons on character building which I know exist.
Whether its gun violence, bullying,  stabbing or fights there has to be a way to teach good morality into the classroom setting. This craziness has to stop. There must be an intentional effort on the part of educators to teach kindness, compassion, decency and positive moral teachings to young children and teens. The Golden Rule should be taught and memorized.
If not, children like Khaseen, and other innocents will continue to die through violence or be bullied to death.
