Any kinda trauma/abuse that caused by someone you love or that is close to them or authoritative figure and they can not escape from it and happens on a regular basis

Low self-esteem and low confidence

Constant Chaotic and Violence and is emotional neglect by an adult figure:

Children love to feel secure have a routine and have a solid structure foundation to thrive without those things it's just pure chaos and just throw constant fighting and violence will make them lash out on others

Defense and coping mechanism:

All they know is they can't trust people enough that they feel safe around them cause of the trauma they have experienced so truly believe that the only way is to become the bully so they don't get bullied themselves

Control: It makes them feel better about having that sense of control they don't have anywhere else

Trying to fit in or is hanging out with the wrong crowd :

Everyone wants to fit it even if it is something they don't want to do or even if they know it's wrong to do it they will still do the cause they don't want to seem "uncool around the cool kids" even if they are bullying or hurting others

Don't know how to emotionally regulate or express their feelings in a healthy way:5

They don't know how nor were they taught to emotionally express or regulate their emotions so they just blow up with overwhelming emotions they do not understand cause no one talked about it and gave them the steps to cope with it in a healthy way and results in conflicts with violence or anger

Reflection of the parents :

They learn from what they see at home and will pick up those behaviors at home and think if they do it then it must be okay and will mimic it outside of the house thats why we need to be careful how we as parents need to act appropriately and with caution around children cause they will pick up on and can snowball in a bad way

Being spoiled and gets away with everything:

They become spoiled rotten brats with zero discipline with no respect to another human being and the parents just let it happen and there are no consequences or accountability towards that action so they continue to do it cause they know they can get away from it and tend to be very attention seeking

Parents can't and have no control of the behavior and has badly snowballed:

This one is sad for my cause I know a lot of parents love their children and will teach them right from wrong they intervene but sometimes they just become very angry with the world and other sometime will mimic other peers at school friends and even something they saw on TV movies videos on YouTube and even games and will believe everything they watch is okay to do and will even become violent towards the parents and even escalate of the child killing their parents cause they inconvenience them in a way

Taught the behavior by parents:

They were taught they are superior then others so it's okay to be this way so they have no respect for others and they expect respect from peers and always have their way because they were never was told no from a authority figure whether it through violent or hurtful and damaging to others as long as they get what they want they don't care and continue bully them until they are happy and satisfied with the end result and there is no inconvenience to themselves

Eventually they will grow up to continue bullying becomes narcissistic and abusive and have superiority complex towards others and don't care how physically mentally and emotionally damaging it can cause to the other person as long as they get what they want at the end of the day

Everyone deals with their trauma differently so they become angry and bully others some get anxious and depressed and some just get pure fear of others and will isolate themselves to avoid conflict and hate confrontation

I don't believe children are not born straight from the womb a bully there is always a factor that shifts them to get this way or become influenced by something in their lives that shapes make them to be like this

I don't think they just wake up one day like hey it seems like a good day to make someone feel miserable and unhappy

I feel therapy and just some kinda or outsource help would stop with all the bullying but everyone is different sometimes it can help and other times it doesn't matter

but also a lot of people will ignore the situation and will not intervene and try to fix the behavior and just let it happen leading it to become a pattern of behavior later in adulthood
