Do you fight Bastila in Knights of the Old Republic

Yes. (SPOILER ALERT) After weeks of torture at Malaks hand Bastila is re educated in the dark side. You confront her on the unknown world inside a temple there she attacks you then tries to convert you, if you are dark and you agree then both of you go on a killing frenzy and slaughter half your party (MU HA HA HA HA). If you are light and she offers you to join her you are forced to continue fighting, she escapes then you confront her on the star forge and have to fight her again. You then choose to kill her or redeem her.
