Not sure if you’re joking, but I think “moving fast and breaking things” is a bit of an understatement. I mean Vader enabled a heartless dictator to take over the galaxy and personally saw to it that a whole planet of billions of people blew up. Doubtless in the years after Order 66 Vader was responsible for millions of other deaths. I mean he personally strangled Captain Antilles for god’s sake.

The Old Republic was flawed, but disruption in this manner was clearly a step towards a new, shittier status quo. Disrupting something and making it worse doesn’t make him a hero.
