Is it true that people who bully are insecure?

This is a common belief; bullies are jealous, or bullies are insecure, or bullies are just repeating what happened to them - these can all be true, but at the same time, it doesn't necessarily have to apply. Bullies are sad people, generally - they seem to get off on hurting other people, physically or mentally. Bullies CAN be jealous, bullies CAN be insecure, bullies CAN be sad - we don't know what goes on behind closed doors. Generally speaking, yes, bullies are insecure, because they sometimes bully a person who has a better quality of life than them. There are many reasons why bullies are who they are - being afraid of them or giving them a reaction is what they want: don't give them what they want!

I believe so. Most bullies only bully others to feel better about themselves. Bullies are most of the time insecure, and think that bringing others down will make them feel better and be better, which is obviously not the case. They may have problems at home or something that not many know about and take their anger, frustration, grief or even sadness out on others. Bullies also may bully because they are jealous of you or somebody and feel that they need to take it out on someone, which may unfortunately be you. If you are a bully, think twice next time before taking it out on others.

Sometimes yes, people who bully others are weak too. So they tend to pick up on someone that they find weaker and less protected than them because they want to gain some sort of power for all time they felt powerless about things happening to them. They release self-hatred and insecurities to people as a form of a coping mechanism to battle their inner insecurities / demons and that is what we called as projection. So remember, if you are being bullied, It's not you being called like that. They are simply releasing their insecurities of themselves to other people.

Hmmm this depends on the person I think. Some people would choose to bully since no one was there to correct their action since they have started. Others may be doing it because, like what you have said, are insecure. In the end, it's not easy to group a person or put a definitive label on them without knowing them properly. They may seem to be like that but sometimes they continue to be like that because of the label and acting to maintain it. Once again, it is different for different people. This is just my opinion on it.
