What 2 Jedi would you have liked to see Fall to the Darkside?

Qui-Gon, it would even fit. Look at it this way, Darth Tyranus was his teacher, and Qui-Gon would believe him about the Republic thing (as he should). Then he would join him believing he would be fighting to stop the corruption of the Republic by joining the dark side. Sid was brilliant, he basically fought a war with himself but did it in a way that the side fighting for the Republic would lose regardless.

Hey Anakin looked up to Qui-Gon and thought about him in AOTC and ROTS. If Qui-Gon went to the dark side so would Ani and maybe Qui-Gon could of killed Obi-Wan and the OT would of been completely different.
