What is violent behavior

When a person harms themselves or others.  Parental abuse, beating up friends or strangers anywhere.  Carrying a fire arm or other weapons and threatening to use it.  Going into rages and trying to harm someone else or even yourself.  Anger outbursts for no apparent reason.  Not being able to hold your liquor and being a mean drunk or being on street drugs and harming others.  Fighting with police if you should be picked up.  I could go on and on, but you get the drift.
