OK, as promised, the pathetic "Darth Malak" was put in his place.
I completed the game on the Dark Side using a Scoundrel type character.
I then decided to play through again with a character more suited to direct combat (I slightly prefer this), and went for the light side ending despite being completely Dark.
I knew that if I threatened to kill Bastilla on top of the temple I would end up with light side points, going from completely dark to around average, so I saved from this point to experiment.
One thing that I find odd is that if you kill Bastilla (and true enough, she was punished for her insolence), she still appears as one of the "heroes" at the end of the game.
Odd considering that I had beheaded her.
Anyhow, in the end, I chose three different scenarios.
I have since read that many were disappointed with the ending, but as far as poor endings go, nothing can beat Mario 64. The Princess bakes you a cake for saving her
😠
I may play Kotor 2, or go through Kotor 1 again with a female character when I get a chance.
