ICE's old (and out of print) Middle Earth Role Playing (MERP) Game had an excellent listing of role, personality, motivation, and alignment traits. If you can pick up a copy of it or download it, it could provide a good resource for what you are looking for.
This is one I put together to give a rough and ready guide for NPC's.
It is, in the main, derived from a system that the late Tony Bath devised for his wargame campaign back in the 1960's.
Interestingly, Tony Bath was a wargamer who was instrumental in the early post war years of wargaming. His forte was Ancients wargaming and as the backdrop for his campaign he used Hyboria! His book, Setting Up a Wargames Campaign, is a fascinating read and he had a lot of articles in the old Battle for Wargamers magazine in the '70s.
To use this system, just deal from a deck of ordinary playing cards as it says. Cancel out any opposites and note the results.
