Good and evil were explained very well in 1969 by Captain Kirk to Yarnek the Lava Creature in the episode, "The Savage Curtain". Although the battle tactics of both the "good" and "evil" sides of the contest were similar, the real difference lay in the nature of the prizes promised to the winner ..., uh, well, that is if you ignore the fact that Yarnek was forcing them to fight and so in reality they had no choice, and thus simple survival was really more of the motivation regardless of any moral direction. So I guess the bottom line is really that the Lava People were sort of evil, even though they did not understand the concept, and in the end they let the Enterprise go in peace and everybody was happy, which was really nice, so uh, hmmm ... by Leira's misty heart, I really don't know anything!
According to James Ohlen's original D&D character sheet (you can see it on Wikipedia!), Minsc has a sister. That's the secret I hope Larian is going to pull out of the hat ... er, helmet.
