As I understand it, narcissists generally prefer a positive pay off, but would generally rather have a big negative than a small positive because they thrive on attention.

At the core is a small worthless-feeling person craving for notice, and yes, love, of a sort. That is why they so often run to needy people. It is very very difficult to have any sort of relationship with a narcissist, or someone displaying those qualities.

We need it tattooing on our foreheads: "narcissism is all about them"
