Jobs was IMO a High-Functioning Sociopath - http://www.md-health.com/Sociopath-Traits.html

He turned his charm on when he need to accomplish something, but there is no real empathy for anyone who was not useful to him in some way. The sad reality of Lisa's situation was that he didn't need her. So he treated her very badly, and then as is typical with sociopaths, turn around and blame her for his behavior. I truly sympathize with her.

What's so fascinating to me is that his narcissism/sociopathy ending up being focused on creating ever-better products, and therefore useful; that strikes me as rare, although it may not be. Wanting to be admired for doing (pushing others to do) actual good work isn't the usual sociopath thing. Maybe the highly unusual example Wozniak showed him, of the excellence humans could achieve (beyond what cut-and-paste engineers could achieve) was the real seed of that trait. Plus enjoying scalding others.
