Narcissists can sometimes be helpful and caring. However, more often than not, they only pretend to have these qualities. Moreover, even when they act giving and helping, they are not motivated by empathy because they severely lack it, and as a result, their help is often not very productive.
Narcissists are motivated by feeling superior and expanding their power, and so the only things that matter when helping others are receiving adulation, fame, influence, opportunities, notoriety, and other resources.
They dont actually care about others because to them other people are just things to use.
Refuse to be treated as a thing.
