Yeah, the big five personality traits fall apart just as easily if you start factoring in evil, yet productive activities.

How does moral relativism play into being agreeable, organized, curious, confident and outgoing? An enterprising individual interested in hooking as many people as possible on heroin? A strong individual that leads Germany out of the economic peril of crushing war debt?

Being superficially agreeable, and conscientious, yet knowingly sabotaging the people you agree with, to their face? Or maybe agreeing with some people, but not with you? Outgoing, but only when met by individuals that meet certain criteria? Curious and inventive, when torturing animals? Organized, while incarcerating inmates in a private prison?

Sounds like a great recipe for being productive at work, just so long as you don't think to deeply about the work being done.
