All their actions point to vengeance. This is puzzling to their victim because they are the innocent by-stander while the narc suddenly strikes with an on slaught of verbal brutality which comes out of nowhere. The narc has this vendetta to punish the perceived wrong done to them. It may have nothing to do with you, it may be a circumstance that aggravates them, possibly anger from childhood abuse, self destructive thoughts or humilation.

Rather than grieve and cringe at their own deplorable conduct, they seem to gloat over their achievement of becoming the most hideous of mankind. The narcissist is attempting to train you into submission.

Trainers drug some animals to make them “manageable” and surgically remove the teeth and claws of others.
