Best role models?
I would think either Carth or Mission. Mission for always cheery personality, stands up for herself ( and others, i.e. You, Zaalbar. ) and has respect. Carth, in the way that he does not turn to the easy path (unlike *one* of his mentors) and is willing to work hard, his sense of humour, and willing to help people.
Most of the people in KotOR are just...angsty, or vicious. Juhani is a nice girl, but she is very introverted, and doesn't care for herself that much. Bastila is way to strict for me to see her as a role model, and Jolee could work as a role model.
DEFINATELY not HK!
