What is Narcissistic Sibling Abuse?

Narcissistic sibling abuse occurs when one sibling consistently uses manipulation, intimidation, and emotional exploitation to control or undermine another. This behavior is rooted in traits of narcissistic personality disorder such as entitlement, lack of empathy, grandiosity, jealousy, and an insatiable need for validation or dominance.

Unlike normal sibling rivalry, narcissistic sibling abuse is one-sided, chronic, and destructive. It’s not about occasional conflict, it's about systematic control.

What Causes Narcissistic Sibling Abuse?

The Golden Child / Scapegoat Roles

In many dysfunctional families, parents unconsciously assign roles to the children, which can lead to favoritism/entitlement in one sibling vs. resentment/insecurity in another sibling. 

Influence of a Narcissistic Parent

Being raised by a narcissistic parent can sometimes lead a child to internalize those dysfunctional patterns and then manifest as abusive behavior toward a sibling.

Competition for Love

In a narcissistic household, affection is scarce. Narcissistic siblings may see their brothers or sisters as threats or competition for love. 

Traits of a Narcissistic Sibling

Emotional Manipulation: gaslighting, silent treatment, guilt tripping

Character Assassination: the narcissistic sibling may spread rumors, twist stories, or intentionally make you look unstable or difficult.

Control and Domination: the narcissistic sibling may insist on being the leader, the star, or the one who decides everything. They may sabotage your achievements out of jealousy.

Public Charm, Private Cruelty: many narcissistic siblings behave perfectly in front of adults, making it even harder for others to believe what’s happening behind the scenes.

Triangulation: a narcissistic sibling will pit family members against each other to secure loyalty and maintain power.

Exploitation: a narcissistic sibling may use you for favors, emotional labor, or money.
