Yeah, I know the stories' overall conclusion is determined by the character's alignment. What I'm wondering is how it's determined. Is it calculated from your character's choices throughout the entire story from the prologue to the finale, or is it determined by your alignment walking into the finale?

I had a question that I wasn't sure of, so I figured I'd ask. I'm in the process of leveling a Jedi Knight (Guardian) and I was wondering how the story's ending was determined around a character's alignment. I know the overall conclusions based on alignment from Youtube and other spoilers, but I was wondering if that was determined by your character's overall actions and choices in the story or if it's determined upon your alignment when you decide to finish the story.
