Narcissistic Rage
So we can see it as a normal reaction to hurt. However, it has
special characteristics because the narcissistic hurt is different
from other types of emotional pain. The fact that this hurt is
very vulnerable, and opens up to an emptiness signifying the dissolution
of identity, imbues the reactive anger with an intensity and hardness
rarely seen in other kinds of anger. (The Point of Existence,
pg 324)

The (narcissitic) rage may turn into, or be accompanied by,
a cold hatred that gives her qualities of power, invincibility,
and calculation. This hatred underlies the desire for vengeance,
for wanting to inflict pain and suffering, and for actually enjoying
getting back at the person who failed her. (The Point of Existence,
pg 327)

Narcissistic rage and envy
The narcissistic
individual, or the normal individual at this phase of development,
is prone to intense anger, an irrational rage, which may take
the form of acute explosions or be chronic and vengeful. This
narcissistic rage is provoked by the slightest—real or
imagined—narcissistic insult, such as not being seen, understood,
or appreciated, in the way one feels he deserves. Narcissistic
envy may arise; one hates anyone who has (or seems to have),
a rich inner life or external acclaim and feels pain about not
having what the other has. (The Point of Existence)
