inferiority complex.

I am sure he has inferiority complex.

Inferiority Complex is a term used to describe people who compensate for feelings of inferiority (feeling like they're less than other people, not as good as others, worthless, etc.) by acting ways that make them appear superior. They do this because controlling others may help them feel less personally inadequate.

According to Alfred Adlar, a feeling of inferiority may be brought about by upbringing as a child (for example, being compared to a sibling), physical and mental limitations, or experiences of social discrimination (for example, having limited opportunities due to race, economic situation, or gender).
