You Need Not Be Tainted Forever

From the Jedi Counselor:

Q: Please clarify the core rulebook's statement that, when gaining a Force Point, a tainted character instead reduces his Dark Side Point total by one. Does this mean that a tainted character may not gain Force Points (except when advancing a level), or does it mean a tainted character can choose to lose a Dark Side Point instead of gaining a Force Point?

A: It means the latter. The sacrifice of a Force Point to lose a Dark Side Point is a choice; it's not automatic.
