Hangar Bombing

"I did it. Because I've come to realize what many people in the Republic have come to realize, that the Jedi are the ones responsible for this War. That we've so lost our way that we have become villains in this conflict, that we are the ones that should be put on trial, all of us! And my attack on the Temple was an attack on what the Jedi have become: an army fighting for the dark side, fallen from the Light that we once held so dear. This Republic is failing! It's only a matter of time."
