What are the real causes of violence and bullying in Schools?

The home is the first school.Children seek to be loved, to belong and to be recognized. Most of the time, when these needs are fulfilled, the child fits into the norm. Sometimes, the parent says something that may trigger violence/bullying. One student whose mother led a 'gentle' life because of overstrict parents told her son not to take any' foolishness' from anybody.I found him to be quick-tempered,sensitive and an instigator of incidents.Whenever he got into trouble and his parent was called in, she defended his actions.She believed he should do unto others before they did something unto him!

I think it's the result of a stressful, chaotic, and oftentimes violent home life.

lack of family nutrients in the home. the nutrients needed to grooms them mentally, socially as well as geer them to be productive. Maybe exposure to violence, experiencing violence. Also due to disfunction within the household, no parental guidance or discipline. Children tend to mimic the same behavior they experience as well as witness, especially if they arent smart enough to do the opposite of whatever they see.
